Two stable silacyclopropenes, 1,1-dimesityl-2,3-bis(trimethylsilyl)-1-silacyclopropene and 1,1-dimesityl-2-phenyl-3-trimethylsilyl-1-silacyclopropene, have been prepared by photolysis of 1,1-dimesityl-1-trimethylsilylethynyltrimethyldisilane and 1,1-dimesityl-1-phenylethynyldisilane, respectively. It has been found that these silacyclopropenes are not affected by atmospheric oxygen, moisture and alcohols
通过1,1的光解反应制备了两种稳定的硅杂环基丙烯,1,1-二甲苯基-1,2,3-双(三甲基硅烷基)-1-硅环丙烯和1,1-二甲苯基-2-苯基-3-三甲基甲硅烷基-1-硅环丙烯。 -二甲硅烷基-1-三甲基甲硅烷基乙炔基三甲基乙硅烷和1,1-二甲硅烷基-1-苯基乙炔基乙硅烷。已经发现这些硅杂环丙烯在室温下不受大气氧,水分和醇的影响。由1-间甲苯基-1-苯基乙炔基四甲基二硅烷的光解法制得的1-间甲苯基-1-甲基-2-苯基-3-三甲基甲硅烷基-1-硅环环丙烯对大气中的氧非常稳定,但容易与苯中的甲醇反应生成环-打开甲氧基硅烷。已经研究了这些硅杂环丙烯的光化学和热行为。
