THE ELECTRON SPIN RESONANCE SPECTRA OF RADICALS PRODUCED BY THE HYDROGEN AND DEUTERIUM BOMBARDMENT OF UNSATURATED ORGANIC COMPOUNDS AT 77K,
Abstract
The radicals produced by the interaction of unsaturated hydrocarbons with hydrogen atoms at 77K have been studied by electron spin resonance (ESR). The hydrogen atom adds directly to the double bond of ethylene, 1,3-butadiene, and benzene to produce the ethyl, 2-butenyl, and cyclohexadienyl radicals respectively. In the case of the interaction of hydrogen atoms with 1-butyne and 1,2-butadiene the methylallenyl radical was observed in each case. On bombardment of 1,4-cyclohexadiene and propyne with hydrogen atoms the cyclohexadienyl and allenyl radicals were observed. These last four reactions can be explained by assuming an addition reaction of hydrogen with the compound. The radical produced immediately abstracts a hydrogen atom from the parent compound to yield the observed stable radical. (Author)
