The Group 14 (Si, Ge, and Sn), Group 15 (P, As, Sb, and Bi), and Group 16 (Se and Te) 2-trimethylsilyl-1-benzometalloles (7) were prepared by the reaction of the corresponding metal reagents with β, o-dilithio-β-trimethyl-silylstyrene intermediate (6), which was derived from phenylacetylene or o-bromoiodobenzene via three steps. The trimethylsilyl group in 7 could be readily removed by treatment with tetrabutylammonium fluoride to give the C-unsubstituted 1-banzometalloles (10).
第14族(Si、Ge、Sn)、第15族(P、As、Sb、Bi)和第16族(Se、Te)的2-三甲基硅基-1-苯基金属富烯(7)是通过相应的金属试剂与β,o-二锂-β-三甲基硅基苯乙烯中间体(6)反应制备得到的,该中间体(6)是通过苯乙炔或邻溴碘苯经过三步反应衍生而来。7中的三甲基硅基可以通过四丁基氟化铵处理方便地去除,得到C未取代的1-苯基金属富烯(10)。
