Abstract
The Pd-catalyzed reaction between β-iodo-β-silylstyrenes and terminal alkynes in i-Pr2NEt gave 1, 2, 3, 5-tetrasubstituted benzenes with complete regioselection. The use of certain silylacetylenes as alkynes enabled efficient synthesis of 1, 3, 5-trissilyl-2-arylbenzenes, which could be transformed into other multisubstituted benzenes by displacement of the silyl groups.
