双核金络合物通过烯烃和尿素的近端和双金属活化,显著地加速了N-烯基尿素的分子内氢胺化反应。具有Au-Au相互作用的Tropos BIPHEP-Au络合物比没有Au-Au相互作用的BINAP-Au络合物具有更高的对映体选择性。
Dinuclear gold complexes significantly accelerate intramolecular hydroamination of N-alkenyl ureas via proximal and bimetallic activation of alkene and urea. Tropos BIPHEP-gold complexes having Au-Au interaction affords higher enantioselectivity than the BINAP-gold counterparts without Au-Au interaction.
