| titleOfInvention | Heterocyclic phosphorus-containing compounds and process for their production |
| abstract | The invention comprises heterocyclic compounds of the formula <FORM:0766766/IV(b)/1> wherein R1, R2, R3 and R4 are H or alkyl, n=0 or 1, and X is chlorine or bromine, and a process for producing them by reaction between a thiophosphonyl chloride or bromide and a 1 : 2- or 1 : 3-alkanediol in presence of a hydrogen halide binding agent, in a hydrocarbon solvent; also a process for chlorinating or brominating the heterocyclic dithiophosphoric acid corresponding, to give the above compounds. In examples, thiophosphoryl chloride reacts with 2 : 2-diethyl-1 : 3-propane diol, 2 - methyl - 2 : 4 - pentane - diol, 2-ethyl - 1 : 3 - hexanediol, and 1 : 2 - propanediol, to give the corresponding 2-chloro-2-thiono - 1 : 3 : 2 - dioxaphospholanes and dioxaphosphorinanes; the 5-ethyl-2-mercapto-4 - propyl - 2 - thiono - 1 : 3 : 2 - dioxaphosphorinane, and the corresponding 5 : 5-diethyl derivative are chlorinated with gaseous chlorine to give the 2-chloro derivatives. Other glycols specified for the formation of the ring compounds include ethylene and butane diols. Specification 759,334, [Group III], is referred to. |
