(1), which was identified by comparison of experimental and calculated (BLYP-6-31G*) IR spectra for both, unlabeled 1 and its perdeuterated isotopomer. Upon irradiation of matrix-isolated silylsilacyclopropenylidene (1) a second C2H4Si2 isomer, namely (silylethynyl)silylene (4) was formed. However, no evidence could be found for the formation of disilatetrahedrane or 1,2- or 1,3-disilacyclobutadiene
脉冲闪热解在组合具有三个前体分子(的基质隔离10,11,12导致形成silylsilacyclopropenylidene的()1),其被鉴定通过实验的比较和计算的(BLYP-6-31G *)IR光谱两者,未标记的1及其全氘化的同位素。在基质分离的甲硅烷基硅烷基环丙烯基(1)的照射下,形成第二种C 2 H 4 Si 2异构体,即(甲硅烷基乙炔基)亚甲硅烷基(4)。然而,没有发现形成二硅四面体或1,2-或1,3-二硅环丁二烯的证据。
