Abstract

Abstract: Hydrogen atoms are generated by mercury photosensitization in an unexceptional apparatus that makes them readily available for organic chemistry on a preparatively useful scale at 1 atm of pressure and temperatures from 0-150'C. The H atoms add to CH,= CH- CH2X to give the intermediate radical CH,-(* CH)-CH, X, which dimerizes to give CH3CH (CH2X)-CH (CH2X) CH3. The saturated substrates CH3CH2CH2X undergo H abstraction ...
