| Abstract: | The mass spectra of the dimethyl and diethyl esters of phosphonic, phosphorochloridic and phosphorochloridothioic acid have been obtained, and the main paths of decomposition of their positiveions have been compared. Losses of formaldehyde occur from positive ions of all the methyl esters. Losses of C2H3˙ radicals occur consistently from the positive ions of the ethyl esters, but diethyl phosphorochloridothioate differs in showing a principal decomposition path involving initial loss of acetaldehyde. Other details are discussed. |
