描述了丙炔与炔烃的高度化学和区域选择性部分分子内铑(I)催化的[2+2+2]环加成反应。可以以良好到优异的产率合成一系列不同的多取代苯衍生物，其中丙二炔充当二炔的合成等价物。当用不对称炔烃处理丙炔时，可以观察到高区域选择性。
A highly chemo- and regioselective partially intramolecular rhodium(I)-catalyzed [2+2+2] cycloaddition of allenynes with alkynes is described. A range of diverse polysubstituted benzene derivatives could be synthesized in good to excellent yields, in which the allenynes served as synthetic equivalent to the diynes. A high regioselectivity could be observed when allenynes were treated with unsymmetrical alkynes.
