Abstract

A palladium-catalyzed Mizoroki-Heck-type reaction ­of aryl trimethoxysilanes with olefins is described. A series of ­ArSi(OMe)3 and olefins, including electron-rich and electron-deficient analogues worked well in the procedure, affording the arylation products in moderate to good yields.

General procedure: Under air, a reaction tube was charged with olefin (0.2 mmol), aryl trimethoxysilane (0.3 mmol), Pd(OAc)2 (2.2 mg, 5 mol%), 1,10-phenanthroline (3.6 mg, 10 mol%), AgF (76 mg, 0.6 mmol) and DMF (2 mL). The mixture was stirred at 60 ˚C. After completion of the reaction (monitored by TLC), EtOAc (20 mL) was added and the mixture was washed with water (10 × 3 mL). Then the organic layer was dried, concentrated in vacuo and the residue was purified by flash column chromatography on a silica gel to give the desired product.
