The reactions of a secondary phosphite with chloro- and pentan-2,4-dionato complexes of iridium(I) and rhodium(I)

Abstract

The secondary phosphite OCH2CMe2CH2OP(O)H reacts with chlorobis(cyclooctene) rhodium(I) dimer to give RhX(R2POHOPR2)2(R2POH) (X=H, Cl) and RhCl2(R2POHOPR2)(R2POH)2 where R2PO = OCH2CMe2CH2PO. The iridium analogue yields corresponding products. The phosphite reacts with bis-(cyclooctene) pentan-2,4-dionatorhodium(I)to give Rh(R2POHOPR2)3 and with the corresponding iridium complex to produce Ir(acac)(R2POHOPR2)2. Some of the complexes act as catalysts or catalytic precursors for the stereoselective reduction of 4-t-butylcyclohexanone. Show more
