Role of Phosphine Sterics in Strained Aminophosphine Chelate Formation
Bowes, Eric G.,Dawson Beattie,Love, Jennifer A.

The preparation of four-membered aminophosphine (PN) chelates from common metal precursors has largely evaded realization because of the ring strain associated with these species. We report a straightforward approach to the synthesis of such PN metallacycles using simple α-PN ligands analogous to the popular class of small-bite-angle diphosphinomethane ligands. It is demonstrated that bulky phosphine substituents are important to the formation of these chelates.
Role of Through Space 2p-3d Overlap in the Alkylation of (ω-N,N-Dimethylaminoalkyl)diphenylphosphines and in the Alkaline Decomposition of Related Quaternary Phosphonium Salts
McEwen, William E.,Smith, Joanne H.,Woo, Edward J.

A series of (ω-N.N-dimethylaminoalkyl)diphenylphosphines has been prepared and subjected to reaction with benzyl chloride in benzene-methanol (60:40 v/v) at 31.0 +/- 0.1 deg C.Each of quaternization reactions was found to follow the second-order rate law,
