molybdenum Fischer carbene complexes with 6-methylene-7-octen-1-yne derivatives at 40 degrees C generates substituted tricyclo[4.3.1.0(1,6)]deca-2,4-dienes in good yield. Pentacarbonyl(butylmethoxycarbene)molybdenum(0) afforded the highest cyclization yields (54%), while the analogous chromium carbene complex gave no reaction. The range of dienyne substrates that participate in this reaction is explored
用6-亚甲基-7-辛烯-1-炔衍生物在40℃下处理钼费希尔卡宾碳烯络合物可产生高收率的取代三环[4.3.1.0(1,6)] dec-2,4-二烯。五羰基(丁基甲氧基卡宾)钼(0)提供最高的环化收率(54%),而类似的卡宾铬络合物则没有反应。探索了参与该反应的二烯炔底物的范围,并分析和讨论了其机理。
