Indium(III) bromide catalyzes efficiently the conjugate addition of indoles to p-benzoquinones under mild conditions to afford the corresponding 3-indolylquinones in high yields with high selectivity. 1,4-Naphthoquinones also underwent Michael addition with indoles under similar conditions to give 3-indolylnaphthoquinones.
