Abstract
This invention relates to a process for manufacturing phosphono imidate compounds corresponding to the formula: ##STR1## wherein R can be selected from alkylene having at least 2 carbon atoms, alkenylene having at least 2 carbon atoms, cycloalkylene, arylene, substituted arylene wherein the substituents can be halo or nitro; R.sub.1 can be alkyl; R.sub.2 can be selected from alkyl, alkenyl, alkynyl, cyano alkyl, aralkyl, alkanoyl alkyl, alkylmercapto alkyl, N-thiazolyl acetamido, phthalimido alkyl, arylthioalkyl, haloarylthioalkyl, thiocyanoalkyl and mixtures thereof.
Claims2
A process for manufacturing a compound having the formula:
- ##STR44## where R is selected from the group consisting of alkylene having 2-3 carbon atoms, alkenylene having 2-3 carbon atoms, cycloalkenylene, arylene, substituted arylene wherein the substituents are selected from halo and nitro;
- R.sub.1 is alkyl having 1-6 carbon atoms;
- R.sub.2 is selected from the group consisting of alkyl having 1-8 carbon atoms, alkenyl having 2-8 carbon atoms, alkynyl having 2-8 carbon atoms, cyano alkyl, aralkyl, alkanoyl alkyl, alkylmercapto alkyl, N-thiazoyl acetamido, phthalimido alkyl, arylthioalkyl, haloarylthioalkyl and thiocyanoalkyl;
- comprising the steps of:
- a. reacting a compound having the formula:
- ##STR45## wherein R is as defined above;
- with a compound having the following generic formula:
- ##STR46## wherein R.sub.1 is as defined above;
- said reaction being carried out in the presence of a tertiary amine;
- b. reacting the product of a) with an organo halide with the formula
- R.sub.2 --X
- wherein X is selected from chlorine, bromine and iodine, and R.sub.2 is as defined above and in the presence of an inert solvent and at a reaction temperature of between 20.degree. C. and 70.degree. C. to form the end product.
