with an organoindium reagent generated in situ from indium and 1,6-dibromo-2,4-hexadiyne in the presence of lithium iodide in tetrahydrofuran (THF) selectively produced 1,6-diols linked to an allenyne unit with complete regioselectivity and chemoselectivity through 1,2-hexadien-4-yn-3,6-ylation, indicating that the organoindium acted as the 3,6-dianion reagent of 1,2-hexadien-4-yne.
醛和酮与铟和1,6-二溴-2,4-己二炔在碘化锂存在下在四氢呋喃(THF)中原位生成的有机铟试剂的反应选择性地生成连接到烯丙炔单元的1,6-二醇通过1,2-己二烯-4-yn-3,6-基化具有完全的区域选择性和化学选择性,表明有机铟充当1,2-己二烯-4-炔的3,6-二价阴离子试剂。
