摘要：

A simple catalytic system for [2+2+2] alkyne cycloadditions consisting of cobalt(II) iodide and zinc powder in acetonitrile was applied to the direct synthesis of hydroxy-alkyl-substituted 1,3-disilaindanes, 1, 4-disilatetralines, and 1,3-disila-1,3-dihydroisobenzofuranes starting front silicon-containing diynes and unprotected propargyl alcohols. Silicon-containg diynes were efficiently coupled with propargyl alcohols with a terminal or internal monoyne moiety. The method reported allows efficient, one-step syntheses of the title Compounds.
