The complex tBu)2(CO)2(PPh3)2> was shown to be an active precursor for the low pressure hydroformylation of terminal alkenes in the presence of an excess of triphenylphosphine.Preliminary kinetic studies have shown that as usual has CO an inhibiting efect, but unexpectedly the reaction was also inhibited by high H2/CO rations.
