Activation of free-radical polyfluoroalkylation of organic substrates with freon BrCF2CF2Br using a system of organic base-electron transfer mediator
摘要:
A polyfluoroalkylation of pyrrole and phenols with freon BrCF2CF2Br using sulfur dioxide-substituted pyridine activating system proceeds at the aromatic nucleus by a free-radical mechanism. The essential influence of the basicity of the medium is demonstrated and discussed. (C) 2009 Elsevier B.V. All rights reserved.
