UV-irradiation of the thiocarbonyl complexFe(CO)2(CS){P(OPh)3}2, prepared from Fe(CO)2(CS2){P(OPh)3}2, affords the unstable thioaldehyde complexFe(CO)2{P(OPh)3}{(PhO)2P(OC6H4)C(H)S}, which reactswith P(OPh)3 to give Fe(CO){P(OPh)3}2{(PhO)2P(OC6H4)C(H)S}, the crystal structure of which reveals an 2(C,S)-bonded thioaldehyde group formally derived from insertion of the thiocarbonyl C atom into an ortho C-H bondof an axially bound P(OPh)3 phenyl group.
