CO2 promoted the RuCl3·3H2O-catalyzed dimerization of phenylacetylene (2) in the presence of PR3 (R = Bu, Cy) and Et2NH to afford 1,4-diphenyl-1-buten-3-yne (3). Et2NCO2RuH(CO)(PCy3)2 (4) and (PhC≡C)2Ru-(CO)(PCy3)2 (5) were isolated by the RuCl3·3H2O/PCy3/ Et2NH/CO2 and 4/2 reactions, respectively, and catalyzed the dimerization of 2 to afford 3 with the concomitant formation of a poly(phenylacetylene).
