P-官能（酰基膦）钨配合物4a-f已通过类膦配合物2a-d与酰氯3a，b的反应以良好的产率制备。酰基（氯）膦络合物4a在-80 ° C下与有机锂试剂的反应选择性地导致锂化的磷酸-烯醇化物络合物5 b的形成。在与亲电试剂如PhC（O）Cl、MeI和Me 3SiCl的反应中证明了该化合物的两亲反应性，其产生O-取代的配合物6a、B和8a、B以及P-取代的配合物7。
P-Functional (acylphosphane)tungsten complexes 4a-f have been prepared in good yields by the reaction of phosphinidenoid complexes 2a-d with acyl chlorides 3a,b. The reactions of acyl(chloro)phosphane complex 4a at -80 degrees C with organolithium reagents selectively led to the formation of lithiated phospha-enolate complex 5b. The ambident reactivity of this compound was demonstrated in reactions with electrophiles such as PhC(O)Cl, MeI, and Me3SiCl, which yielded O-substituted complexes 6a,b and 8a,b and P-substituted complex 7.
