Phosphinomethyl zirconium(III) complexes as hydrogenation catalysts of specific selectivity
Abstract
Zirconium(III) complexes containing the chelated [graphic omitted]Ph2 moiety hydrogenate unsaturated hydrocarbons in a rapid catalytic process with specific selectivity, giving a quantitative yield of cyclo-octene from 1,3- and 1,5-cyclo-octadiene and of 1,2,3,4-tetraphenylbutane from diphenylacetylene.
