Perchlorovinylcarbene: a bulky electrophile
Abstract
The carbene selectivity index mcxy for perchlorovinylcarbene [Cl2CCClC(Cl):] was determined by competition experiments with different substituted olefins as ∼0.38, whereas the value calculated from Moss's equation is 0.34 ± 0.1; this proves at least qualitatively that perchlorovinylcarbene is an electrophilic carbene.
