Abstract
(−)-2,3-O-Isopropylidene-2,3-dihydroxy-1,4-bis(diphenylphosphino)buthane(diop) was found to be an efficient chiral ligand on using in Ru(II) catalyzed enantioselection of racemic alcohols with unsaturated additives. The dehydrogenation of PhEtCHOH by Ru2Cl4((−)-diop) with PhCH=CHCOPh at 165°C resulted in the formation of S-(−)-PhEtCHOH(11.0%e.e. at Conv.=56.8%).Keywords
