methods to prepare aryl nitriles and vinyl nitriles from arylhalides and alkynes, respectively. Using inexpensive and non-toxic 4-cyanopyridine N-oxide as the cyano shuttle, the methods provide an efficient approach to prepare aryl cyanides and vinyl nitriles under mild and operationally simple reaction conditions with a broad range of functional group tolerance. In hydrocyanation of alkynes, the method
This report describes a new method for three-component difluoroalkylation and trifluoromethylthiolation/trifluoromethylselenolation of π-bonds via air-stable SCF3 and SeCF3 reagents as free-radical initiators of ethyl iododifluoroacetate.
