Abstract

Abstract: A dinuclear (electron-deficient η5-cyclopentadienyl) rhodiumACHTUNGTRENNUNG (III) complex was synthesized on a preparative scale via the rhodium-catalyzed cross [2+ 2+ 1] cyclotrimerization of silylacetylenes and two alkynyl esters, leading to substituted silylfulvenes, followed by reductive complexation with rhodiumACHTUNGTRENNUNG (III) chloride in ethanol. The thus obtained dinuclear( ...
