A versatile methodology, involving readily available starting materials, allows for the synthesis of stable hemilabile bidentate cyclic (alkyl)(amino)carbenes (CAACs) featuring alkene, ether, amine, imine, and phosphine functionalities. The stability of the free carbenes has been exploited for the synthesis of copper(I) and gold(I) complexes. It is shown that the pendant imine moiety stabilizes the
一种涉及容易获得的起始材料的通用方法允许合成具有烯烃、醚、胺、亚胺和膦官能团的稳定的半稳定双齿环状(烷基)(氨基)卡宾 (CAAC)。游离卡宾的稳定性已被用于合成铜 (I) 和金 (I) 配合物。结果表明,悬垂的亚胺部分稳定了金 (III) 的氧化态,并使联苯撑的 CC 键氧化加成到相应的阳离子金 (I) 配合物上。后者和相应的铜(I)配合物对α-甲基苯乙烯与N,N-二甲基苯胺的加氢芳基化显示出高催化活性,铜(I)配合物以高选择性促进苯乙炔的抗马尔科夫尼科夫加氢肼化。
