1-dimesitylsiliranes, stable at room temperature over months, have been synthesized from the addition of dimesitylsilylene to 2,3-dimethylbutadiene, 2-methylbutadiene, trans, trans-2,4-hexadiene, cis, cis-2,4-hexadiene, cis, cis-2,4-hexadiene, and cis,-trans-2,4-hexadiene. Addition of dimesitylsilylene to the π bond of the diene was stereospecific as indicated by 29 Si NMR. Secondary photodecomposition of 2-vinylsiliranes
通过将二甲基亚硅烷添加到 2,3-二甲基丁二烯、2-甲基丁二烯、反式、反式-2,4-己二烯、顺式、顺式中,合成了七个 2-乙烯基-1,1-二甲基硅烷,在室温下可稳定数月-2,4-己二烯、顺式、顺式-2,4-己二烯和顺式-反式-2,4-己二烯。如 29 Si NMR 所示,二甲苯基亚甲硅烷向二烯的 π 键的加成是立体有择的。含有一个乙烯基氢 α 到硅烷环的 2-乙烯基硅烷的二次光分解产生 2,3-二烯基硅烷。由含有反式、反式-2,4-己二烯、2,2-二甲基六甲基丙硅烷和反式-2-甲基-3-的溶液光解形成顺式-2,5-二甲基-1,1-二甲基硅杂环戊-3-烯( 1-trans-propenyl)-1,1-dimesitylsilirane 是立体定向的
