Smooth natural synthesis has paid a lot realization to the chemistry of small carbocycles. Vinylidenecyclopropanes (VDCPs), that have strained cyclopropyl team attached with an allene moiety and but are thermally good and reactive components in natural chemistry, are flexible intermediates in natural synthesis. during this quantity, Dr. Lixiong Shao, Dr. Jianmei Lu and Prof. Dr. Min Shi assessment their investigations at the chemistry of VDCPs, typically together with the education, the reactivities upon therapy with Lewis or Brønsted acid, in addition to transition steel catalysts and a few different miscellaneous analogues. The contributions aroused a renaissance of cationic intermediates within the chemistry of VDCPs.
