Herein it is shown, for the first time, that enolonium species are powerful electrophiles capable of reacting with aromatic compounds in an intermolecular manner to afford α-arylated ketones. The reaction is compatible with a variety of functional groups, is of wide scope with respect to aromatic compounds and ketone, and even works for polymerization-prone substrates such as substituted pyrroles,
在此首次表明,en烯是能够以分子间方式与芳族化合物反应以提供α-芳基化酮的强亲电试剂。该反应与多种官能团相容,对于芳族化合物和酮而言具有广泛的范围,甚至适用于易于聚合的底物,例如取代的
吡咯,
噻吩和
呋喃。仅需要1.6至5当量的商品芳族底物。
