Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Tri(naphthalen-1-yl)phosphine, is researched, Molecular C30H21P, CAS is 3411-48-1, about Complexes of gold(I) and platinum(II) with polyaromatic phosphine ligands.Synthetic Route of C30H21P.
Au and Pt(II) complexes of the phosphine ligands PArnPh3-n (Ar = naphthyl, anthracenyl, ferrocenyl and other polyaromatic groups) were synthesized. The electron donating abilities of naphthyl and anthracenyl phosphine ligands was explored using gas phase photoelectron spectral data on the parent phosphines and their relative complexing ability to Pt precursor mols. was assessed by synthetic studies and NMR experiments Their steric parameters were estimated by the Tolman cone angle methodol. using x-ray crystallog. data. The mol. structures of the Au complexes [AuCl(PAn2Ph)]·CHCl3 and [Au(PFc2Ph)2]·CHCl3 were determined
