Abstract

Alkenyl halides are versatile reagents, which not only act as efficient alkenyl electrophiles but are also readily converted to strong alkenyl nucleophiles upon treating with a metal such as magnesium or lithium. Synthesis of alkenyl halides 1 from alkenyl triflates, which can be prepared regioselectively from readily available ketones or aldehydes, 2,3 is beneficial but no facile and general way has been reported. 4 Considering their high reactivity towards alkenyl triflates, 5 transition ...
