✦ Synopsis

Synthesis of Hindered and Functionalized 1-CF3 Substituted Olefins via a Carbolithiation-Elimination-Metalation Cascade.

-Trisubstituted fluoroalkenes of type (III) are obtained stereoselectively. They react further with organolithium reagents and undergo vinyl metalation to give, after trapping with an electrophile, tetrasubstituted olefins with high yield and selectivity. -(BEGUE,
