1,2-Dihalocyclopentenes on reaction with alkali metals and chlorotrimethylsilane in hydrocarbon or ether solvents produce silylated 1-pentynes by ring opening. Sodium metal and hydrocarbon solvents favour the cleavage most. Different mechanistic aspects are considered.
1,2-二卤代环戊烯与碱金属和氯三甲基硅烷在烃或醚溶剂中的反应通过开环产生甲硅烷基化的1-戊炔。金属钠和碳氢化合物溶剂最有利于裂解。考虑了不同的机械方面。
