Synthesis, Reactivities, and Coordination Chemistry of Tris(2‐isopropoxyphenyl)phosphine

ABSTRACTA phosphine bearing three 2‐isopropoxyphenyl groups, P{C6H4[2‐O(i‐Pr)]}3 (1), was synthesized. Phosphine 1 readily reacted with CH2Cl2 and ClCH2CH2Cl at 25°C to give the corresponding phosphonium salts [RCH2P{C6H4[2‐O(i‐Pr)]}3]X (2: R=X=Cl, 3: R=CH2Cl, X=BF4). Platinum, palladium, and rhodium complexes with ligand 1, [PtCl2(1)2] (4), [PdCl2(1)2] (5), [{PdCl(1)}2(μ‐Cl)2] (6), and [RhCl(cod)(1)] (7) were synthesized and their structures were determined by X‐ray crystallography, which revealed that ligand 1 works as a monodentate ligand in these complexes.
