The tetrasubstituted ethylene, bifluorenylidene, reacts very rapidly (4.06*10-2 l mol-1 sec-1 at 0 deg C) with HCo(CO)4 to give bifluorenyl. α-Phenylacrylonitrile (atroponitrile) reacts even more rapidly under the same conditions (6.0 l mol-1 sec-1).Other highly substituted ethylenes react very slowly with HCo(CO)4, indicating considerable steric effects.The data are consistent with radical type intermediates.
