Conversion of CS2 to Thioaldehyde at a Single Iron Center
摘要:
UV-irradiation of the thiocarbonyl complex Fe(Co)(2)(CS){P(OPh)(3)}(2), prepared from Fe(CO)(2)(CS2){P(OPh)(3)}(2), affords the unstable thioaldehyde complex. Fe(CO)(2){P(OPh)(3)}{(PhO)(2)P(OC6H4)C(H)S}, which reacts with P(OPh)(3) to give Fe(CO) {P(OPh)(3)}(2){(PhO)(2)P(OC6H4)-C(H)S} the crystal structure of which reveals an eta(2)(C,S)bonded thioaldehyde group formally derived from insertion of the thiocarbonyl C atom into an, ortho C-H bond of an axially bound P(OPh)(3) phenyl group.
