Popis: | The precatalyst [Cp*RuCl(cod)] promotes the head-to-head cyclodimerization of propargylic alcohols and the formation of novel alkylidene cyclobutenes (see scheme; Cp*=C5 Me5 , cod=1,5-cyclooctadiene) by addition of carboxylic acid to the Ru(η4 -cyclobutadiene) intermediate and dehydration. |
