Abstract
Compounds of the general formula: <FORM:0844402/IV(b)/1> in which R and R1 are C1-C4 alkyl groups which may be the same or different, R2 is hydrogen or an alkyl, aralkyl, or aryl group, and R3 is an alkyl, aralkyl, or aryl group are obtained by reacting an amine of the general formula: <FORM:0844402/IV(b)/2> wherein R2 and R3 are as defined above with a halogeno acid halide of the formula XCH2CO.Y where X and Y are halogen atoms, preferably both chlorine atoms, in water to form a watersoluble intermediate of the general formula: X.CH2CO.N(R)2(R3),X, R2 and R3 being as defined above, and then, without isolation reacting this intermediate in aqueous solution with a phosphorodithioic acid ester salt of the formula (RO)(R1O)P(S)SM wherein M is a monovalent metal atom and R and R1 are as defined above. The temperature in the first step of the process should not, in general, exceed 20 DEG C. and on completion of the reaction with the amine any precipitated solid may be re-dissolved by addition of further quantities of water, the compound of the formula (RO)(R1O)P(S)SM added and the mixture allowed to stand, if desired with stirring, at room temperature or heated to complete the reaction. The compound of the last given formula can be added as a ready made metal salt or a compound in which M is hydrogen can be used and the appropriate quantity of alkali added to form the salt in situ. Examples are given for the production of products in which R and R1 are ethyl, R2 is hydrogen and R3 is isopropyl and methyl respectively and in which R and R1 are methyl, R2 is hydrogen and R3 is methyl. Specificatio 791,824 is referred to.
