A silver(I) triflate-catalyzed reaction of 1-((cyclopropylidenemethyl)-2-alkynyl)arene with 2-alkynylbenzaldoxime

A silver(I)-catalyzed reaction of 1-((cyclopropylidenemethyl)-2-alkynyl)arene with 2-alkynylbenzaldoxime leads to 1-((1,3-dihydroisobenzofuran-1-yl)methyl)isoquinolines in good to excellent yields. A radical process is believed to be involved in the transformation.
