资源简介：
The
dinuclear gold(II,II) and gold(III,III) complexes [Au2(μ-PY)2(MeCN)2]OTf2 (2-OTf2) and [Au2(μ-PY)2(μ-CH2)(MeCN)2]OTf2 (3-OTf2) (PY = [(CH2)2PPh2]−) have been synthesized
and evaluated as Lewis acid catalysts for Mukaiyama addition and alkyne
hydroamination reactions. 2-OTf2 and 3-OTf2 provide similar
or improved catalytic activity for these reactions compared to the
commonly used gold(I) Lewis acids Ph3PAuOTf and IPrAuOTf.
The versatile Lewis acidity of 2-OTf2 was further demonstrated by its superior performance in a
cascade reaction involving intramolecular hydroamination followed
by intermolecular conjugate addition to generate a 2,3-substituted
indole.
