Chiral iridium complex catalyzed a formal [4+2] cycloaddition of biphenylene with disubstituted alkynes, which was initiated by carbon-carbon bond cleavage. Axially chiral 9,10-disubstituted phenanthrenes were enantiomerically obtained.
手性铱配合物催化亚联苯与双取代炔烃的正式 [4+2] 环加成反应,该反应由碳-碳键断裂引发。对映体获得了轴向手性 9,10-二取代菲。
