The products of the addition of toluene-p-sulphonyl iodide to substituted phenylacetylenes (and styrenes) are studied. The regiospecificity and stereoselectivity of trans addition to acetylenes is inferred from 1H n.m.r. spectroscopy. The effect of s

The effect of substituents and temperature on the reactivity of a) arylacetylenes towards arenesulphonyl radicals and b) ar enesulphonyl chlor ides towards substituted phenyl radicals, was studied. Arenesulphonyl radicals were prepared from photolysi

Absolute rate constants for addition reactions of arylthiyl radicals (YC6H4S˙) to arylacetylenes (XC6H4CCH) have been determined by a flash-photolysis method. The rate constants (in dm3 mol–1 s–1) vary from 1.0 × 105(X =m-NO2 and Y =p-MeO) to 1

Free-radical reactions have been for long time the domain of the physical chemists and the basic chemical industry (polymerization of vinyl monomers, oxidation by molecular oxygen, chlorination of methane etc.), where the use of simple molecules and
