Reactions of O,O-Dialkyldithiophosphork Adds with Non-Activated α-Olefins

摘要

Electrophilic addition reactions of O,O-dialkyldithiophosphoric acids to non-activated α-olefins proceeding in accordance with the Markovnikov's rule were studied. In the absence of a catalyst these reactions occur very slowly to give the products in low yields, while Lewis acid as a catalyst can greatly accelerate the reaction and increase the conversion in the AdE-processes. A similar acceleration of the addition processes and an increase in the reaction product yield occur at the action of ultrasound on the reaction medium.
