Pentaphenylphosphole, reaction with iron

Interaction of pentaphenylphosphole with iron pentacarbonyl gives rise to the tiVp) complex 190 [61JA4406 77JOM( 136)241 79ICA(35)231]. On the other hand, reaction of Ec3(CO)l2 leads to the formation of the V complex 191 and... 

Ligands containing phosphorus, arsenic, or antimony as the donor atom do not cause disproportionation of iron carbonyls, and fairly stable, simple substitution products are obtained. The direct reaction, carried out either thermally or photochemicaUy, with any of the three iron carbonyls, has yielded the complexes [Fe(CO)4L], with L = P(C6Hs)3 12, 35, 214, 215, 125a), P[N(CHj)2]3 71), pentaphenylphosphole 216,21, As(C6Hs)j 12,...
