Utilizing proton transfer to produce molecular salts in bromanilic acid substituted-pyridine molecular complexes-predictable synthons?

Controlled introduction of proton transfer into the design of a series of molecular complexes is described, delivering the systematic production of ionic molecular complexes (molecular salts). The controlled production of molecular salts has relevance as a potential strategy in the design of pharmaceutical materials. In nine molecular complexes consisting of bromanilic acid with the N-heterocyclic compounds 2-, 3-and 4-picoline [bis(2/3/4-methylpyridinium) 2,5-dibromo-3,6-dioxocyclohexa-1,4-diene-1,4-diolate, 2C6H 8N+¡¤C6Br2O4 2-], 2,3-, 2,4-, 2,5-and 3,5-lutidine [2,3/2,4/2,5/3,5- dimethylpyridinium 2,5-dibromo-4-hydroxy-3,6-dioxocyclohexa-1,4-dien-1-olate, C7H10N+¡¤C6HBr 2O4 -], and 3-bromo-4-methylpyridine [3-bromo-4-methylpyridinium 2,5-dibromo-4-hydroxy-3,6-dioxocyclohexa-1,4-dien-1- olate, C6H7BrN+¡¤C6HBr 2O4 -] and 2-bromo-3-methylpyridine [2-bromo-3-methylpyridine-2,5-dibromo-3,6-dihydroxycyclohexa-2,5-diene-1, 4-dione (1/1), C6H6BrN¡¤C6H 2Br2O4], proton transfer occurs readily between the bromanilic acid molecule and the N heteroatom of the pyridine ring, in all cases producing a charge-assisted bifurcated N-H…O hydrogen bond. This reinforces the value of this motif as a design tool in the crystal engineering of such complexes. The protonation state (and stoichiometry) significantly affect the supramolecular synthons obtained, but 1:2 stoichiometries reliably give rise to PBP synthons and 1:1 stoichiometries to PBBP synthons (where P indicates a methylpyridine co-molecule and B a bromanilic acid molecule). The influence of halogen interactions on the wider crystal packing is also discussed, with C-H…Br and Br…O interactions the most prevalent; only one Br…Br interaction is found.

Influence of steric effect on the structural aspects of N,N?,N?-triarylguanidine derived six-membered [C,N] palladacycles

Guanidine derived six-membered [C,N] palladacycles of the types [(C,N)Pd(mu-OC(O)R)]2 (1a-d), [(C,N)Pd(mu-Br)]2 (2a,b), cis-[(C,N)PdBr(L)] (3a-d, 4, and 5), and ring contracted guanidine derived five-membered [C,N] palladacycle, [(C,N)PdBr(CNXy)] (6) were prepared in high yield following the established methods with a view aimed at understanding the influence of the substituents on the aryl rings of the guanidine upon the solid state structure and solution behaviour of palladacycles. Palladacycles were characterised by microanalytical, IR, NMR and mass spectral data. The molecular structures of 1a, 1c, 2a, 2b, 3a, 3c, 3d, and 4-6 were determined by single crystal X-ray diffraction data. Palladacycles 1a and 1c were shown to exist as a dimer in transoid in-in conformation in the solid state but as a mixture of a dimer in major proportion and a monomer (kappa2-O, O?-OAc) in solution as deduced from 1H NMR data. Palladacycles 2a and 2b were shown to exist as a dimer in transoid conformation in the solid state but the former was shown to exist as a mixture of a dimer and presumably a trimer in solution as revealed by a variable temperature 1H NMR data in conjunction with ESI-MS data. The cis configuration around the palladium atom in 3a, 3c, and 3d was ascribed to steric influence of the aryl moiety of NAr unit and that in 4-6 was ascribed to antisymbiosis. The solution behaviour of 3d was studied by a variable concentration (VC) 1H NMR data.

Design and synthesis of tridentate facially chelating ligands of the [2.n.1]-(2,6)-Pyridinophane family

Syntheses are reported for tripyridine macrocycles 2 and 3 and some of their alkyl derivatives. The macrocycles are designed to stabilize to various extents coordinated d8 metal precursors and d6 alkane oxidative addition products (ptIV), therefore allowing favorable kinetics and thermodynamics of (e.g., PtII) the cleavage of substrate H-C(sp3) bonds. Both the Chichibabin protocol and oxidative coupling of carbanions by copper(I) iodide were used for the macrocyclization step. Crystal structures of singly and doubly protonated 2 establish atom connectivity in the macrocycle, and reveal structural features which are obscured in solution NMR by rapid proton migration.

Oxidative degradation of aqueous amine solutions of MEA, AMP, MDEA, Pz: A review

Alkanolamine based post-combustion capture processes (PCC) are currently the most attractive technologies for CO2 capture. Solvents are degraded in this service by flue gas components, for example oxygen. Solvent degradation can be classified into two reaction types: 1) amine oxidative degradation through a) autoxidation pathways, b) oxidation in the presence of metal ions and 2) thermal degradation including reactions in the presence of CO2. This study represents a literature survey of oxidative degradation (reaction type 1a) of 2-Amino-1-ethanol (MEA), 2-Amino-2-methyl-1- propanol (AMP), N,N-Bis(2-hydroxyethyl)methyl-amine (MDEA), and Piperazine (Pz). Thermal degradation products (reaction type 2) are included where appropriate in order to contribute to a more complete degradation overview of these compounds.
