Abstract
Various primary nitro compounds have been treated with KH in tetrahydrofuran and then with Me 3 SiSSiMe 3 to give potassium thiohydroxamates. These salts were neutralized by an acid and then desulphurized by light to afford nitriles in 78-87% yields. In these reactions, Me 3 SiSSiMe 3 acted as a 'counterattack reagent'.
