A-Phenylthiocarbonyl compounds

On the other hand, the coaddition of thiyl radicals and oxygen to olefins, a process termed cooxidation [41], is an attractive method to obtain access to peroxyl radicals, that is, the thiyl radical adduct is captured by oxygen. The final products depend on the nature of the starting materials. Selected examples of the addition of PhSH and O2 to alkenes are given in equations (11)-(15). The first two are used as entry to a-phenylthiocarbonyl compounds starting either from alkenyl sulfides [42] or alkenyl silanes (electroinitiation) [43]. Equations (13) and (14) are used for the synthesis of )5-hydroxysulfoxides [44,45] and equation (15) is an example of synthesis of five- and six-membered cyclic peroxides [46,47].
