Earlier unknown 1,3-bisketene organoelement derivatives RMeE(C(E ’Me3)=C=O)2 (E = Si, Ge; E’ = Si, Ge, Sn) have been synthesized by the reaction of bis(alkoxyethynyl)silanes and -germanes with Me3E’Hal. Bis(1-trimethylsilyl-2-oxovinyl)silane is also formed by the reaction of trimethylsilyl- and (dimethylsilylene)bisketenes with dimethylsilylene bistriflate and trimethylsilyl triflate, respectively. Addition of nucleophiles to the ketene fragment of compounds synthesized has been studied.
之前未知的1,3-双烯基烯烃有机元素衍生物RMeE(C(E’Me3)=C=O)2(E = Si, Ge; E’ = Si, Ge, Sn)通过双(烷氧基乙炔基)硅烷和-锗烷与Me3E’Hal的反应合成。此外,双(1-三甲基硅基-2-氧代乙烯基)硅烷也是通过三甲基硅基-和(二甲基硅烯)双烯烃与二甲基硅烯双三氟甲磺酸酯和三甲基硅基三氟甲磺酸酯分别反应生成的。对合成化合物中烯烃片段的亲核试剂的加成进行了研究。
