- W41061704 abstract "By treating 1-heptyne with n-butyllithium, converting the 1-heptynyllithium formed into 1-heptynylmetal derivatives with various metals, and reacting them with o-tolyl iodide in the presence of palladium-phosphine complexes, e.g., Pd(PPh/sub 3/)/sub 4/, at 20/sup 0/C, excellent yields of arylalkyne products were obtained via alkynyl-aryl cross-coupling with heptynylmetal derivatives containing tin, boron (as borate), and particularly zinc. Heptynyl alkali metal derivatives were ineffective. This procedure was then successfully used for selective and highly stereospecific synthesis of terminal enynes by the reaction of alkynylzinc chlorides with alkenyl halides, but the analogous alkynyl-alkynyl reaction between 1-heptynylzinc chloride and 1-hexynyl iodide or bromide gave a nearly statistical mixure of C/sub 12/, C/sub 13/, and C/sub 14/ diynes. An indirect procedure was developed for the synthesis of both terminal and internal conjugated diynes. Nickel-phosphine complexes gave much lower yields (50 of acetylenic products)." @default.
