N2 - Solutions of [(C6H5)3P]3CoCH3 (I) in C6H5Cl yield biphenyl, triphenylphosphine, methyldiphenylphosphine and diphenylphosphine. In 4-ClC6H4CH3, 4-methylbiphenyl and 4,4′-bitolyl form as well. Solutions of I in C6H6, C6D6, C6H5CH3, C6H5Br yield only triphenylphosphine and biphenyl, while in 4-FC6H4I 4,4′-difluorobiphenyl is formed but no biphenyl. The cobalt compound is recovered as (Ph3P)nCoX or as CoX2 (XCl, Br, I, n = 3 or 2) from reactions with arylhalides. The results are rationalized in terms of the very strong tendency for I to undergo oxidative addition reactions.
