Abstract

(figure presented) Methylalumoxane (MAO) was found to be an active catalytic precursor for the chemo- and regioselective dimerization of a wide range of aryl-and alkyl-substituted terminal alkynes yielding the corresponding geminal dimers A. For an olefin-functionalized terminal alkyne (RC≡CH, R = MeC=CH2), the geminal dimer undergoes an intermolecular [4 + 2] cycloaddition forming compound B.
