摘要：

The coupling of an alkynyl and a butadienyl unit at the rhodium center of 1 is the key step in the selective, stepwise trimerization of methyl propiolate HCCR to hexadienyne 3 with [Rh(η2‐O2CMe)(PiPr3)2] as a metal template. In MgCl2 in ether, this step occurs almost quantitatively, and the intermediates 1 and 2 were characterized by X‐ray crystal structure analysis. (Figure Presented.)
