Abstract

In an attempt to regenerate Ti(0) from TiOx for possible application in a catalytic McMurry coupling reaction, a praseodymium-based pinacol reaction was uncovered. This reaction formed the two products 2,3-diphenyl-2,3-butanediol (3) and α,β-dimethyl-α-phenyl-β-[(trimethylsilyl)oxy]-benzene-ethanol (6) in a 1:3 ratio.
