The phosphatriafulvenes 3a,b, accessible from the cyclopropenone 1 and the lithium phosphides 2, possess inverse electron density as indicated by structure B; this can also be deduced from calculations. In accord with the electronic structure, methyllithium attacks at a carbon atom of the three-membered ring (to ), carboxylic acid chlorides effect -acylation (to 6), and dimethyl acetylenedicarboxylate
的phosphatriafulvenes 3A,3B,从cyclopropenone访问1和锂磷化物2,具有由结构所指示的逆电子密度乙; 这也可以从计算中得出。根据电子结构,甲基锂攻击三元环的碳原子(至),羧酸氯化物进行酰化(至6),而乙炔二羧酸二甲酯插入P / Si键(至8)。
