Mild Pd/Cu-catalyzed sila-sonogashira coupling of (hetero)aryl bromides with (hetero)arylethynylsilanes under PTC conditions
Bellina, Fabio,Lessi, Marco
, p. 773 - 777 (2012)
The palladium/copper cocatalyzed sila-Sonogashira reaction of (hetero)arylethynysilanes with (hetero)aryl bromides in toluene and water at 40 C under PTC conditions gave the required di(hetero)arylethynes in moderate to high yields. Activated, deactivated and ortho-substituted (hetero)aryl bromides are well tolerated. This protocol also allowed the preparation of symmetrical diarylethynes by double arylation of 1,2-bis(trimethylsilyl)ethyne. Georg Thieme Verlag Stuttgart · New York.
