Alkenyl triflates in combination with Co(acac)(3) as a catalyst were found to be excellent coupling partners of alkynyl Grignard reagents, where no special additives (even a phosphine ligand) but a common solvent, THF, are required to obtain variously substituted enynes.
已发现烯基三氟甲磺酸酯与作为催化剂的三乙酰丙酮钴（III）相结合时，是炔基格氏试剂的优良偶联伙伴，在此反应中，无需特殊添加剂（甚至膦配体），仅需常用溶剂四氢呋喃（THF）就能得到各种取代的烯炔。
