Abstract

Selective Dehydrogenation of Alcohols and Diols Catalyzed by a Dihydrido Iridium PCP Pincer Complex.-The title complex catalyzes the transfer dehydrogenation of primary and secondary alcohols to afford the corresponding aldehydes and ketones in most cases as sole products in quantitative GC yields. Diol (V) gives an unexpected cyclopentenone under this iridium catalysis. With methanol the dihydridoiridium complex forms a carbonyl complex.
