UNUSUAL STERIC EFFECT OF AN ALKENYL OR ARYL GROUP ON THE DISSOCIATIVE REDUCTIVE ELIMINATION FROM cis-ALKENYL(OR -ARYL)DIMETHYL(TRIPHENYLPHOSPHINE)GOLD(III)

A sterically bulky aryl or alkenyl group directly bonded to gold suppresses the rate of dissociation of the triphenylphosphine ligand from cis-alkenyl(or -aryl)dimethyl(triphenylphosphine)gold(III) leading to selective reductive elimination.
Steric and electronic effects of the tertiary phosphine ligand on the dissociative reductive elimination from cis-aryldimethyl(triarylphosphine)gold(III)

A series of cis-aryldimethyl(triarylphosphine)gold(III) complexes, cis-Au(C6H4Y)Me2(P(C6H 4X)3) (X = p-OMe, p-Me, H, p-F, o-Me; Y = p-OMe, p-Me, H, p-F, o-OMe, o-Me) and AuPhMe2(P(C6H4-O-Me)nPh 3-n) (n = 0-2), has been prepared by the alkylation of cis-AuMe2IL by the corresponding Grignard reagents. Electron withdrawal from and the steric bulk of the triarylphosphine ligand as well as electron donation by the aryl ligand enhances phosphine dissociation, leading to a facile and selective reductive elimination of aryl Me.
