Electron-transfer substitution at a saturated carbon atom is now well established. 2 Although most of the known examples are chain processes, it is of interest that the first example of an electron-transfer substitution process to be recognized (1964) 3 was the non-chain reaction of eq 1, which had been discovered in 1961.4 The mech-anism proposed in 1964 (eq 2-4) invoked collapse of a radical and an anion to give a radical anion, an idea that, while ...
