Modern organic synthesis has paid much attention to the chemistry of small carbocycles.
Vinylidenecyclopropanes (VDCPs) which have strained cyclopropyl group connected with an allene
moiety and yet are thermally stable and reactive substances in organic chemistry are versatile
intermediates in organic synthesis. In this volume Dr. Lixiong Shao Dr. Jianmei Lu and Prof.
Dr. Min Shi review their investigations on the chemistry of VDCPs mainly including the
preparation the reactivities upon treatment with Lewis or Brønsted acid as well as transition
metal catalysts and some other miscellaneous analogues. The contributions aroused a renaissance
of cationic intermediates in the chemistry of VDCPs.
