Abstract
A significant kinetic effect of the placement of gem-dialkyl substituents in the carbon backbone of a bidentate phosphine ligand on a reductive elimination reaction involving chelate opening as a preliminary step has been documented. This observation confirms the viability of the gem-dialkyl effect as a mechanistic probe for preliminary phosphine dissociation in reactions of complexes containing chelating diphosphine ligands.
