Abstract

Cationic chiral monophosphines are devised as a novel type of ligands for catalytic transformations of polar substrates with polar reagents. A phosphonio-phosphine derived from (R, R)-diop ('methyldiopium') proved to act as a chiral version of Baird's ω-phosphonio- phosphine ligands ('phophos') in Rh (I) complexes in both 1: 1 and 2: 1 P: Rh stoichiometry. Their versatile structure in CDCl3 solution has been studied by NMR spectroscopy in the ...
