Zeolite-entrapped osmium carbonyl clusters: selective and stable catalysts for CO hydrogenation

Abstract

[H₂Os(CO)₄] is converted in the pores of a basic form of zeolite Y (formed by treatment with NaN₃)to give entrapped Os carbonyl clusters that catalyse CO hydrogenation at 573 K and 19 bar (1 bar = 10⁵ Pa) to give C₂—C₄ hydrocarbons in high yield with only slow loss of catalytic activity and selectivity.
