Abstract

Compounds of the general formula <FORM:0981213/C2/1> in which R1 is a hydrogen atom or an alkyl, aralkyl, or cycloalkyl group and R2 is an alkyl, aralkyl or cycloalkyl group are obtained by subjecting a compound of the general formula <FORM:0981213/C2/2> wherein R1 and R2 are as defined above to isomerization by heating and recovering the isomerized product. The heating is preferably effected at between 120 DEG and 200 DEG C. The invention also includes as new products compounds of the first given general formula above but excluding those in which both R1 and R2 are alkyl groups. Examples are given for the production of compounds of the first-given general formula above in which (1) R1 and R2 are ethyl, (2) each R1 is hydrogen and R2 is benzyl, and (3) R1 and R2 are benzyl. The product in which each R1 is hydrogen and each R2 is benzyl is obtained in the example by adding an ethereal solution of trimeric phosphonitrilic chloride to a solution of sodium in benzyl alcohol at 0 DEG C., filtering, diluting with ether, and washing the extract with dilute aqueous solutions of HCl, sodium bicarbonate and water. The starting material of the second general formula above in which R1 and R2 are each ethyl is obtained by dissolving trimeric phosphonitrilic chloride in pyridine, stirring and cooling the solution and adding ethanol slowly while maintaining the temperature at 0 DEG to 5 DEG C. The starting material in which R1 and R2 are each benzyl is obtained by refluxing dry benzyl alcohol with a solution of sodium in dry ethanol in a column until the ethanol is removed, replacing the ethanol by dry dioxane and adding a benzene solution of trimeric phosphonitrilic chloride to the refluxing alkoxide.
