The reaction of the phosphonium metallates Me4P[C5R5(CO)(Me3P)MC(O)=CHC(O)R′] (M = W, R = H, R′ = Et (1a); M = Mo, R = Me, R′ = Me (1b)) with the silylating reagent Me3SiOSO2CF3 yields the neutral complexes C5R5(CO)(Me3P)MC(OSiMe3)=CHC(O)R (2a, 2b) bearing a chelating O(2), C(4)-trimethylsiloxybutenone ligand. The structure of the new compounds is established by the IR, 1H and 31P NMR spectra.
phospho的金属化反应使Me 4 P [C 5 R 5(CO)(Me 3 P)MC(O)= CHC(O)R'](M = W,R = H,R'= Et(1a) ; M = Mo,R = Me,R'= Me(1b))与甲硅烷基化试剂Me 3 SiOSO 2 CF 3产生中性络合物C 5 R 5(CO)(Me 3 P)MC(OSiMe3)= CHC( O)R(2a,2b)带有螯合的O(2),C(4)-三甲基甲硅烷氧基丁烯酮配体。新化合物的结构由IR,1 H和31 P NMR光谱确定。
