Cyclic organophosphorus compounds as possible pesticides. Part I. 1,3,2-Dioxaphospholans
Abstract
Butane-2,3-diol and 2,3-dimethylbutane-2,3-diol have been converted into substituted 2-mercapto-2-thiono-1,3,2-dioxaphospholans, and thence into 2-(N-substituted carbamoylmethyl)thio-derivatives. Some new ring-substituted 1,3,2-dioxaphospholans, with alkoxy, alkylthio, and dimethylamino groups attached to phosphorus, have also been prepared from aliphatic 1,2-diols. The hydrolytic stability and insecticidal activity of the esters are briefly discussed.
