Liquid enol ethers and acetates as gaseous alkyne equivalents in rh-catalyzed chemo- and regioselective formal cross-alkyne cyclotrimerization.
A cationic rhodium(I)/rac-BINAP complex catalyzes chemo- and regioselective formal cross-cyclotrimerizations of alkynes with enol ethers or acetates. Commercially available and cheap liquid enol ethers and acetates could be used as convenient gaseous alkyne equivalents in the present rhodium catalyses.
