摘要：

Reactions of the phosphorus-bridging carbonyl derivative (i-Pr2NP)2COFe2(CO)6 with the phosphonium methylides R3P = CH2 (R = Me, Me2N, Ph, p-toly) in diethyl ether at room temperature do not result in the formation of the corresponding olefin [(i-Pr2NP)2C = CH2]Fe2(CO)6 in a typical Wittig olefination reaction. Instead, the stable 1:1 adducts [(i-Pr2NP)2HCOCHPR3]Fe2(CO)6 are formed. X-ray diffraction on (i-Pr2NP)2HCOCHP(C6H4Me-p)3]Fe2(CO)6 (monoclinic, space group P2(1); a = 10.925 (6) angstrom, b = 14.822 (4) angstrom, c = 14.581 (6) angstrom, beta = 109.05 (3)-degrees-C, Z = 2) indicates that the phosphorus-bridging carbonyl group has acylated the ylide carbon atom in R3P = CH2 to give a new type of phosphonium acylmethylide.
