Abstract
1445968 Free radicals L H SUTCLIFFE and M R BRINKMAN 19 July 1973 [21 July 1972] 34320/72 Heading C2C The invention comprises free radicals containing the moity which may form part of a fused ring structure, and also secondary free radicals when formed from said free radicals on heating or prolonged storage. The radicals of the above formula are prepared by reacting an olefinic compound with tetrasulphur tetranitide to form an adduct and breaking this down, e.g. by U, V or gamma irradiation or heat, a typical reaction scheme being Other adducts prepared similarly and then decomposed to free radicals have the formulµ (or possibly isomeric forms) The free radicals are used for spin labelling.
