Co2(CO)8 and Co4(CO)12 in benzene solution at 150 °C catalyze hydrogen transfer from either of the donors 9,10-dihydroanthracene or 9-fluorenol to the hydrogen acceptor 1,1-diphenylethylene; in the process anthracene and fluorenone are formed, respe

The tetrasubstituted ethylene, bifluorenylidene, reacts very rapidly (4.06 X 10−2 1 mol−1 sec−1 at 0°C) with HCo(CO)4 to give bifluorenyl. α-Phenylacrylonitrile (atroponitrile) reacts even more rapidly under the same conditions (6.0 l mol−s

The results of a study of the reactions of HCo(CO)4 and HMn(CO)5 with a variety of a substituted cyclopropenes are consistent with the formation of the intermediate caged radical pairs; recombination in the cage of the radical pair leads to hydroform

We report here the first example of a stoichiometric hydroformylation using HMn(CO) 5 . Treatment of a hexane solution of 1,2-diphenyl-3,3-dimethylcyclopropene with HMn(CO) 5 at 55°C gave after 5 h a 27% yield of aldehydes, 87% cis and 13% trans . T

9-Methylideneflourene (IIa) reacts rapidly with HCo(CO)4 at -67° C to give a quantitative yield of 9-methylfluorene (IIIa); k2 (13.4 ± 0.5) × 10-2 l mol-1 S-1. Although the internal olefin, 9-ethylidenefluorene (IIb) reacts more slowly than II

Several new transition metal complexes of the cyclopentadienyl ylides (CpPPh3, CpSMe2, and CpPy are reported. Reactions of CpSMe2 with MnCl2, FeCl2, CoCl2 and NiX2 (where X=d or Br) leads to complexes in which the ylide:metal halide stoichiometry is

Rate data for the stoichiometric radical hydrogenation of four conjugated aromatic olefins with HCo(CO)4 and DCo(CO)4 were obtained and the activation parameters deterimined. The kinetic isotope effect, kHkD, varied from 0.43 with ethylidenefluorene
