摘要

A cross-coupling reaction of allyl halides 1 with alkynyltins 3 in the presence of “Ni (PR3),”(R= Ph, OEt, or OPh) catalyst was carried out in THF at reflux to give 1, benynes. The regioselectivity of the coupling of If-i with 3a was investigated in the presence of various phosphorus ligands. Interestingly, prenyl (lj) and geranyl chlorides (lk) selectively reacted with 3 at the more-hindered positions of substituted q3-allylnickel intermediates 21 (M= Nil ...
