Zn/[bmim]PF6-mediated Markovnikov allylation of unactivated terminal alkynes

A simple and highly regioselective method has been developed for the allylation of unactivated terminal alkynes with allyl bromide using Zn/[bmim]PF6 as an inexpensive, readily available and recyclable reagent system. High conversions and enhanced selectivity together with the environmentally benign nature of the Zn/[bmim]PF6 reagent system makes this method an attractive alternative to established methods.
