Triazine-wingtips accelerated NHC-Pd catalysed carbonylative Sonogashira cross-coupling reaction
Keyword(s):
The transmetalation as the rate-limiting step was effectively accelerated by newly designed N-heterocyclic carbenes with triazine wing-tips (T-NHC). By using ppm-level precatalyst T-NHC-Pd (8), the highly efficient coupling of aryl...
