[Ir6(CO)15]2– in NaX zeolite: catalyst for carbon monoxide hydrogenation
Abstract
[Ir(CO)2(acac)](Hacac = pentane-2,4-dione) in the pores of NaX zeolite was converted in the presence of CO into [HIr4(CO)11]– or [Ir6(CO)15]2–; the sample containing the latter is catalytically active for CO hydrogenation, giving high yields of alkenes
