| abstract | The invention comprises a process for the production of monovinyl or b -substituted monovinyl esters of phosphoric or a phosphonic acid of the formula: <FORM:0784985/IV (a)/1> in which R1 is a substituted or unsubstituted alkyl, aryl, alkoxy or aryloxy group, R2 is a substituted or unsubstituted alkoxy or aryloxy group, R3 and R4 are hydrogen or a substituted or unsubstituted alkyl, aryl, alkoxy or aryloxy group by the reaction of a tertiary phosphite or secondary phosphonite of the general formula: <FORM:0784985/IV (a)/2> R being substituted or unsubstituted alkyl, with an a -monohalogenated aldehyde. Alkyl halide is eliminated between the reactants. In examples, triethyl - phosphite, trischlorethyl phosphite and bis 2(21-methoxyethoxy) ethyl benzene phosphonite, react with chloracetaldehyde to give diethyl vinyl phosphate, bischlorethyl vinyl phosphate, and 2-(21-methoxy ethoxy) - ethyl vinyl benzene phosphonate. Other products specified include chloroalkyl and chlorbenzyl products at R4. |
