Heck Vinylation of Aryl Iodides by a Silica Sol−Gel Entrapped Pd(II) Catalyst and Its Combination with a Photocyclization Process

Silica sol−gel encaged PdCl2(PPh3)2 is a recyclable catalyst for the Heck vinylation of aryl iodides. It is possible to couple the Heck reaction with photocyclization in a one-pot process
