Reductive Coupling by Chromium(0) - (Bibenzyl)- and (Stilbene)tricarbonylchromium(0) Complexes by a One-Pot Reaction from Benzylic Halides

Reaction of Cr(CO)3(NH3)3 with benzylic mono-, di-, and trihalides leads to the formation of 1,2-diarylethanes, -ethenes, and diphenylethyne in satisfactory yields.Di(halomethyl)benzene derivatives yield product mixtures containing both reduction products and coupling products.With a higher excess in chromium(0), under otherwise unchanged reaction conditions, the corresponding (arene)tricarbonylchromium(0) complexes of the coupling products are formed in a one-pot reaction from the benzylic halides.
