Abstract 2-Mercapto-2-thiono-1, 3, 2-dioxaphospholanes and dioxaphosphorinanes, have been synthesized by the reactions of phosphorus pentasulphide with some 1, 2-diols (viz., butane-2, 3-diol and 2, 3-dimethylbutane-2, 3-diol) and 1, 3-diols (viz., 2-methylpentane-2, 4- diol, 2, 2-dimethylpropane-1, 3-diol and 2, 2-diethylpropane-1, 3-diol) in 1: 2 molar ratio in dry benzene. These volatile compounds have been purified by distillation under reduced ...
