Dichlorocarbene generated in a two-phase catalytic system reacts with 3-trimethylsilyl-2,5-dihydrofuran to give both possible products of mono-insertion into the CH bond in positions 2 and 5 of the ring, together with a CC bond adduct. Reaction of 2-trimethylsilyl-4,5-dihydrofuran with dichlorocarbene leads to 2,3-dichloro-2-trimethylsilyl-5,6-dihydro-2H-pyran, which is formed via isomerization of
在两相催化体系中生成的二氯卡宾与3-三甲基甲硅烷基-2,5-二氢呋喃反应,生成单插入到环2和5位的CH键中的两种可能产物,以及CC债券加合物。2-三甲基甲硅烷基-4,5-二氢呋喃与二氯卡宾的反应生成2,3-二氯-2-三甲基甲硅烷基-5,6-二氢-2 H-吡喃,其是通过伯双环加合物的异构化形成的。
