摘要：

The reaction of trialkylphosphines with 7-phosphanorbornadiene PW(CO)5 complexes affords the corresponding phosphoranylidenephosphine complexes R13P=P(R)→ W(CO)5. One such complex (R = CO2Et, R1 = Et) has been investigated by X-ray crystal structure analysis. It shows a zwitterionic character with a long P=P bond(2.156 (2)Å). These phosphoranylidenephosphine complexes cleanly react at room temperature with aldehydes to give the corresponding phosphaalkene complexes via a “phospha-Wittig” reaction. These phosphaalkene complexes are either isolated as such or trapped by MeOH, dimethylbutadiene, or benzoic acid. © 1990, American Chemical Society. All rights reserved.
