Notes:
Mono-substituted triphenyl-phosphine, -arsine and -stibine derivatives of phenylmethinyltricobalt enneacarbonyls PhCCo3(CO)8L (where L = PPh3, AsPh3 and SbPh3) were synthesized. The Co(2p3/2) binding energy (Eb) was lowered from 781.3 eV in PhCCo3(CO)9, to 780.0 eV in PhCCo3(CO)8PPh3, to 780.3 eV in PhCCo3(CO)8AsPh3 and to 780.5 eV in PhCCO3(CO)8SbPh3. Hydroformylation selectivity to total aldehyde and alcohol of the substituted clusters PhCCo3(CO)8L was about 100%, but that of the parent cluster PhCCo3(CO)9 was 93.8%. Hydroformylation products of styrene and di-isobutene were the completely normal aldehyde when using PhCCo3(CO)8AsPh3 as catalyst.
