Abstract

Results Rate Constants for the Addition of the Phenyl Radical to Pyridine Derivatives. 4- Cyanopyridine has been utilized as a substrate for several reasons: it is significantly more reactive than unsubstituted pyridine, the reaction is quite clean at the low conversions required by the competitive method, only two isomers are formed (2-phenyl-and 3-phenyl-4- cyanopyridine), and the GLC analysis is particularly simple. The chlorine atom abstraction ...
