REDUCTIVE ELIMINATION OF DIHYDROGEN FROM ARENECHROMIUM DIMERS
Bitterwolf, Thomas E.
, p. 305 - 316 (1983)
Biphenylbis(chromium dicarbonyl)-μ-bis(diphenylphosphido)methane and its arsenic analog have been prepared in good yield by UV irradiation of biphenylbis(chromium tricarbonyl) and bis(diphenylphosphido)methane or bis(diphenylarsino)methane in benzene.Addition of strong acid to these dinuclear compounds results in rapid dihydrogen evolution and subsequent decomposition of the oxidized chromium species.A scheme for the dihydrogen elimination reaction is proposed in which both metal centers are protonated in an oxidative addition step, followed by reductive elimination of dihydrogen from the two metal centers.
