  Highly Efficient and Selective Synthesis of Conjugated Triynes and Higher Oligoynes of Biological and Materials Chemical Interest via Palladium-Catalyzed Alkynyl−Alkenyl Coupling

  摘要：

  Iteration of a Pd-catalyzed reaction of alkynyl- and oligoynylzincs with (E)-ICH-CHCI followed by metalation-termination with electrophiles(E) has provided a linear route to conjugated tri- and tetraynes, and Pd-catalyzed monoalkynylation of 1,1-dibromoenynes accompanied by dehydrobromination has provided a convergent route to conjugated tri-, tetra-, and pentaynes. Both display unprecedented high efficiency and selectivity.
