The 1,1-dialkoxy derivatives of 2,5-diphenylsilacyclopent-3-ene were prepared by a one-pot reaction of magnesium with (E,E)-diphenyl-1,3-butadiene and dialkoxydichlorosilanes. The trans content in each silacyclopentene was higher than the cis content. Hydrogenation of these silacyclopentenes gave the corresponding silacyclopentanes in high yields.
通过镁与(E,E)-二苯基-1,3-丁二烯和二羰基二氯硅烷的一锅反应,制备了 2,5-二苯基硅基环戊-3-烯的 1,1-二烷氧基衍生物。每种硅环戊烯的反式含量都高于顺式含量。对这些硅杂环戊烯进行氢化处理,可以得到相应的高产率硅杂环戊烷。
