Abstract
T-Butyl o-methylthio- and o-phenylthioperoxybenzoates-[C=17O] were prepared and decomposed thermally in chlorobenzene. The oxygen labels were detected by 17O NMR spectroscopy preferentially at the carbonyl oxygen of 3,1-benzoxathian-4-one and diphenyl 2,2′-dithiodibenzoate, demonstrating the bridged sulfuranyl radical structures for the o-thiobenzoyloxy radicals.This publication has 4 references indexed in Scilit:
