A direct dehydroxylative and decarboxylative coupling between a large number of allylic alcohols and alkynoicacids was realized affording 1,4-enyne motifs in high efficiency. In this reaction, calcium-promoted C–OH bond cleavage was crucial, which facilitated the sequential decarboxylation, and thus enabled the palladium-catalyzed allyl–alkynyl coupling, which occurred in an environmentally benign

Synthesis of 1,4-enynes was performed via nickel-catalyzed cross-coupling of allylicalcohols with alkynylzinc reagents. The reaction features high regio- and E/Z-selectivity when aryl-substituted allylicalcohols were employed. The method also exhibits a wide scope of substrates and good compatibility of functional groups.
