  Highly Activated Vinyl Hydrogen in a Significantly Twisted Styrene

  摘要：

  The novel example of a vinylic hydrogen more reactive than a benzylic hydrogen was found by treatment of a twisted styrene derivative with a strong base followed by D2O quenching. In this paper, the full details of the examples of the highly activated vinyl hydrogens in twisted styrene derivatives are described, with a discussion on the correlation between the reactivity of the vinyl hydrogens and the magnitude of the twist. The highly reactive vinyl hydrogens could be rationalized by considering the novel orbital interaction between the pi* orbital of the benzene ring and the sigma orbital of the vinylic C-H bond in the twisted styrene derivatives.

  Vinyl hydrogen more reactive than benzyl hydrogen toward base in significantly twisted styrenes

  摘要：

  The novel example of vinyl hydrogen more reactive than benzylic hydrogen was found by treatment of a twisted styrene derivative with a strong base followed by D2O quenching. The characteristic nature of the vinyl hydrogen, which is activated by sigma-pi* orbital interaction, was apparently demonstrated. (C) 2001 Elsevier Science Ltd. All rights reserved.
