New complexes of functionalised ligands bearing P/N/Se or P2Se donor sets

Supramolecular chemistry of half-sandwich organometallic building blocks based on RuCl2(p-cymene)Ph2PCH2Y

“…We have previously found that Mannich based condensation reactions are extremely facile for the syntheses of functionalised tertiary and ditertiary phosphines [29][30][31][32][33][34]. Carboxylic acid phosphines [32,34] can be prepared by this procedure and furthermore, we have shown some of these ligands serve as convenient building blocks for the preparation of linear, dinuclear gold(I) complexes [35] with unusual finite and infinite structures.…”

“…We are unaware of any systematic studies exploring the supramolecular chemistry of RuCl 2 (p-cymene)(PR 3 ) with phosphines from a similar ligand library. As part of ongoing studies in our group [29][30][31][32][33][34][35] we have used Mannich-based condensation reactions as an excellent procedure for synthesising highly functionalised tertiary and ditertiary phosphines. Herein we describe the use of isomeric, carboxylic acid or mixed phenol/carboxylic acid containing tertiary phosphines, Ph 2 PCH 2 Y, for the preparation of a range of RuCl 2 (p-cymene)(Ph 2 PCH 2 Y) complexes.…”

Phosphines and Related Tervalent Phosphorus Systems

“…Among new phosphinoarylimines reported are those from 2-aminomethylpyridine, 379 1-phenylazo-2-naphthylamine, 380 chiral sulfinamides, 381,382 chiral monosulfonamido derivatives of trans-1,2-diaminocyclohexane, 383 and the primary amines H 2 N(CH 2 ) n SePh (n¼3,4). 384 Imine formation with o-diphenylphosphinobenzaldehyde has also been used for the surface functionalisation of dendritic primary alkylamines, giving dendrimeric P,N ligands. 385 Aminal-and thioacetal-like cyclocondensations of o-diphenylphosphinobenzaldehyde with chiral amino-amides, disecondary amines, and 3-hydroxypropanethiols has afforded new chiral phosphines, e.g., (162), 386,387 and (163).…”

Synthesis of platinum, palladium and rhodium complexes of α-aminophosphine ligands

“…N-Phenylselenoalkyl-bis(aminophosphines), a special family of ligands, were also utilized as bidentate P-ligands in the synthesis of Pt II and Pd II complexes (Scheme 25). 64 According to X-ray studies, the products were of cis configuration, and the metal centre was in a nearly square planar geometry.…”
