Dilithiation of Fe(C5H4CHMeNMe2)(C5H5) (1) with BuLi is predominantly homoannular but with BuLi/TMED is heteroannular. Heteroannular dilithiation predominates in the reaction of BuLi/TMED with Fe(C5H3(CHMeNMe2)SiMe3-1,2)(C 5H5), Fe(C5H3(CHMeNMe2)SiMe 3-1,2)(C5H4SiMe3), and Fe(C5H2(CHMeNMe2) (SiMe3)2-1,2,3,)(C5H4SiMe 3) (11). The lithioferrocenes react with ClSiMe3 to afford isolable products although some mixtures of isomers are difficult to characterize. The [3]ferrocenophane Fe(C5H3(CHMeNMe2)S3-1,2,3)(C 5H4) is obtained from 1 as are [Fe(C5H5)(C5H3(CHMeNMe 2)-1,2)]xQ (x = 2, Q = PPh; x = 1, Q = SMe; x = 1, Q = PPhCMe3 (only one diastereomer because of strong chiral induction)) and Fe(C5H4CHMeNMe2)(C5H 4AsPh2). Crystals of 11 are monoclinic: a = 17.800 (2) A, b = 11.760 (1) A, c = 13.931 (2) A, beta = 107.142 (5), Z = 4, space group P21/n. The structure was solved by conventional heavy-atom methods and was refined by full-matrix least-squares procedures to R = 0.054 and Rw = 0.061 for 2745 reflections with I ? 3sigma(I).

One-pot reaction of FcCH(R)OH with equimolar quantities of BunLi and EtOCOCl followed by an excess of amine produces N-(alpha-ferrocenylalkyl)amines in up to 98% yields. Nitrogen heteroaryl amines undergo the alpha-ferrocenylalkylation at the amino group. The alpha-ferrocenylalkylation of alcohols and phenols (R’OH) leads to a formation of ethers FcCH(R)OR? in lower yields. The reactions proceed via an intermediate formation of alpha-ferrocenylalkyl carbonates FcCH(R)OCOOEt. The side reactions associated with this protocol are discussed.

A series of new copper complexes containing chiral ferrocenyl diphosphine ligands of the Josiphos family have been prepared. These complexes have been studied in the catalytic asymmetric 1,2-addition of Grignard reagents to enones and aromatic ketones. Variation of the electronic and steric properties of the ligand resulted in a positive effect in the regio- and enantioselectivity of Grignard reagents to alpha-H-substituted enones using the ligand in which tert-butyl substituents were introduced in the diarylphosphine moiety. The copper complexes were also successfully applied in the catalytic asymmetric conjugate addition of Grignard reagents to enoates. No increase of enantioselectivity was observed in the catalytic asymmetric addition of linear Grignard reagents, compared to that of the commercially available ligand rev-Josiphos.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. 31886-57-4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 31886-57-4, in my other articles.

Ferrocenyltrithiocarbonates (I) are readily obtained by treating alpha-ferrocenylcarbinols (II) successively with sodium hydride, carbon disulfide and alkyl halide.Formation of I occurs by intramolecular nucleophilic displacement of oxygen by sulfur with retention of configuration.This is supported by the nature of the other products formed and by the X-ray structure determination of an optically active compound I, which was refined to R = 0.038.The title compound of R configuration was obtained from (R)-ferrocenylmethylmethanol.

Corresponding salts have been synthesised. The pKb has a marked influence on their chemistry. Protonation competes with complexation but cis-PtCl2L2 L=1-3, 5, 7, and cis-Pt(N-N)Cl2 L=8, 9, have been characterised. Two reversible couples [Fc+A/FcA], [Fc+AH+/FcAH+] (A=amine function) and an irreversible oxidation/protonation of A are linked by a EECE mechanism, but potentials for the first two are independent of the amine and similar to ferrocene. Nucleophilic attack by ferrocenylamines at the nitrile, protonation and ligand substitution are all observed with cis-[PtCl2(NCR)2].

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst.

The efficient syntheses of novel planar chiral 1,3-diamines and 1,3-amino ethers with an oxy or amino function directly bound to the cyclopentadienyl ring of ferrocene has been developed. The key reaction is the Cu2O promoted substitution of of (pR)-diisopropyl-2-iodoferrocenecarboxamide with either phthalimide or AcOH to introduce nitrogen or oxygen functionality onto the cyclopentadienyl ring. The enantiomerically pure iodoferrocene derivative is available from the known enantioselective ortho-lithiation of N,N-diisopropylferrocenecarboxamide with n-BuLi sparteine, In the course of these studies the synthesis of a novel C2 symmetric C-2 dimer of N,N-dimethyl-1-ferrocenylethylamine was characterised by single crystal X-ray diffraction.

The typical design of chiral electroactive materials involves attaching chiral pendants to an electroactive polyconjugated backbone and generally results in modest chirality manifestations. Discussed herein are electroactive chiral poly-heterocycles, where chirality is not external to the electroactive backbone but inherent to it, and results from a torsion generated by the periodic presence of atropisomeric, conjugatively active biheteroaromatic scaffolds, (3,3-bithianaphthene). As the stereogenic element coincides with the electroactive one, films of impressive chiroptical activity and outstanding enantiodiscrimination properties are obtained. Moreover, chirality manifestations can be finely and reversibly tuned by the electric potential, as progressive injection of holes forces the two thianaphthene rings to co-planarize to favor delocalization. Such deformations, revealed by CD spectroelectrochemistry, are elastic and reversible, thus suggesting a breathing system. A jolt upon recognition: Torsion in the electroactive backbone endows poly-heterocycle films with high chiroptical activity, which is reversibly tunable by the electric potential, and outstanding enantiorecognition capability with about 100 mV between two enantiomeric ferrocenyl amino probes, in any order, in alternating sequences, and as a racemate.

Starting from (eta5-acetylcyclopentadienyl)(eta4-tetraphenylcyclobutadiene)cobalt(I), highly enantioselective (99 % ee) (S)-CBS catalysed ketone reduction followed by stereospecific alcohol-azide exchange, azide reduction and dimethyllation gave (R)-(eta5-alpha-N,N-dimethylaminoethylcyclopentadienyl)(eta4-tetraphenylcyclobutadiene) cobalt(I) (Arthurs? amine). This underwent highly diastereoselective cyclopalladation to give di-mu-acetate-bis-(R)-[(eta5-(Sp)-2-(alpha-N,N-dimethylaminoethyl)cyclopentadienyl, 1-C, N)(eta4-tetraphenylcyclobutadiene)cobalt(I)]dipalladium, and highly diastereoselective lithiation to give (R)-(eta5-(Sp)-1-(alpha-N,N-dimethylaminoethyl)-2-(diphenylphosphino)cyclopentadienyl)(eta4-tetraphenylcyclobutadiene)cobalt(I) (PPCA) following the addition as electrophile of chlorodiphenylphosphine. This PN-ligand was converted into (R)-(eta5-(Sp)-1-(alpha-dicyclohexylphosphinoethyl)-2-(diphenylphosphino)cyclopentadienyl)(eta4-tetraphenylcyclobutadiene)cobalt(I), a PP-ligand (Rossiphos), by stereospecific amine-phosphine exchange using HPCy2. These air-stable P?N and P?P complexes are the first examples of a new class of bulky planar chiral ligands for application in asymmetric catalysis.
