5,10-Dimethyl-6,8-bisdehydropentatridecafulvalene 11, 10-methyl-6,8-bisdehydro-4,5-benzopentatridecafulvalene 12, 6,8-bisdehydro-4,5:10,11-dibenzopentatridecafulvalene 13, 5,10-dimethyl-6,8-bisdehydropentapentadecafulvalene 14, 7,12-dimethyl-8,10-bisdehydropentaheptadecafulvalene 15, and 7,12-dimethyl-8,10-bisdehy-dropentanonadecafulvalene 16 were synthesized through the reaction of the corresponding bisdehydroannulenones 1–6 with cyclopentadienide. The tropic nature of these pentafulvalenes is discussed on the basis of 1H NMR and electronic spectra as well as those of the corresponding heptafulvalene derivatives.
5,10-二甲基-6,8-二脱氢十五烯 11, 10-甲基-6,8-二脱氢-4,5-苯并十五烯 12, 6,8-二脱氢-4,5:通过相应的双脱氢丙酮 1-6 与环戊二烯的反应,合成了 6,8-二脱氢-4,5:10,11-二苯并五碳十三烯、5,10-二甲基-6,8-二脱氢五碳十四烯、7,12-二甲基-8,10-二脱氢五碳十五烯 15 和 7,12-二甲基-8,10-二脱氢五碳十六烯。根据 1H NMR 和电子光谱以及相应的七富勒烯衍生物的光谱,讨论了这些五富勒烯的热带性质。
