As part of our ongoing interest in the homolytic reactivity of thionitrites, 4 we have previously shown that the capture of nitric oxide from a thionitrite by a carbon centered radical can be a very effective step in a free radical chain reaction, presumably via a propagative addition–elimination mechanism. With this observation in mind, and also given the rapid and reversible addition of thiyl radicals to alkenes, we were especially intrigued by the potential behaviour of tertiary ...
