  Cationic Rhodium(I) Complex-Catalyzed Cotrimerization of Propargyl Esters and Arylacetylenes Leading to Substituted Dihydropentalenes

  摘要：

  It has been established that a cationic rhodium(I)/cod complex catalyzes the cotrimerization of propargyl esters and arylacetylenes, leading to substituted dihydropentalenes, in the presence of excess cod through elimination of carboxylic acids.
