Abstract
The invention comprises compounds of the general formula: <FORM:0944406/C2/1> wherein (A) when m is 1 and n is zero, R1 is a hydrogen atom, a C1-8 saturated or unsaturated aliphatic hydrocarbon or an aryl or aralkyl group, R2 is a C1-8 saturated aliphatic hydrocarbon or an aryl or aralkyl group, and R3 and R4 are each hydrogen atoms or C1-8 saturated or unsaturated aliphatic hydrocarbon groups or aralkyl groups; (B) when m is 1 and n is 1, either (a) R1 and R2 are both hydrogen atoms, in which case R3 is a C1-8 saturated or unsaturated aliphatic hydrocarbon or an aralkyl group, and R4 is a C2-8 saturated or unsaturated aliphatic hydrocarbon, an aryl or an aralkyl group, or (b) R3 and R4 are both hydrogen atoms, in which case R1 and R2 are each a C2-8 saturated or unsaturated aliphatic hydrocarbon group or an aryl or aralkyl group; and (c) when m is 2 and n is zero or 1, R1 and R2 are each a hydrogen atom, or a C1-8 saturated or unsaturated aliphatic hydrocarbon, an aryl or an aralkyl group and R3 and R4 are each a C1-8 saturated or unsaturated aliphatic hydrocarbon, an aryl or an aralkyl group, and the preparation thereof (a) (when m is 1 and n is zero or 1) by treating an appropriate diol with an excess of thionyl chloride with or without an inert solvent, heating the resulting mixture under reflux, and thereafter removing excess thionyl chloride and solvent, if used, to obtain the desired ester; or by reacting the appropriate diol with an exact equivalent of thionyl chloride in an inert solvent, with or without heat, thereafter removing the solvent to obtain the desired ester, or by reacting a mixture of the appropriate diol, a base and an inert solvent with thionyl chloride, preferably at between -20 DEG and -30 DEG C., and thereafter recovering the desired ester from the reaction mixture; or (b) (when m is 2 and n is zero or 1) by oxidising the corresponding sulphurous acid ester in an appropriate solvent with an oxidising agent.
