Abstract:
Disclosed is a method for producing alkoxycarbonylamino triazines of formula (I) by reacting diaminotriazines or triaminotriazines with cyclic carbonic acid esters and optional subordinate quantities of acyclic carbonic acid esters in the presence of an alcohol and an alkaline alkanol or alkaline-earth alkanol as a base. In said formula, Y represents hydrogen, C1-C4 alkyl, phenyl that is optionally substituted by C1-C4 alkyl, C1-C4 alkoxy, or halogen, or a radical of formula NR R while R , R , R , R , R , and R independently represent hydrogen or a radical of formula COOX or X, wherein X represents C1-C13 alkyl, the carbon skeleton of which can be interrupted by 1 or 2 oxygen atoms having the function of ether and/or substituted by hydroxy, or C3-C6 alkenyl provided that at least one of the radicals R to R in formula (I) represents COOX, or at least one of the radicals R to R in said formula represents COOX if Y represents NR R .
Abstract:
In a process for preparing alkoxycarbonylaminotriazines, di- or triaminotriazines are reacted with cyclic carbonic esters and optionally with minor amounts of acyclic carbonic esters in the presence of an alcohol and of an alkali metal alkoxide or alkaline earth metal alkoxide as a base.

Abstract:

Abstract:
Production of alkoxycarbonylamino-triazine compounds comprises reaction of a triazine with carboxylic acid esters in the presence of an alcohol and a base. The triazine is reacted with dimethyl carbonate and a 2-13C alcohol whose hydrocarbon group contains ether groups, in the presence of an alkali or alkaline earth methanolate as base. Process for the production of alkoxycarbonylamino-triazine compounds of formula (I) comprises reaction of a triazine of formula (II) with carboxylic acid esters in the presence of an alcohol and a base. The triazine of formula (II) is reacted with dimethyl carbonate and a 2-13C alcohol whose hydrocarbon group contains ether groups, in the presence of an alkali or alkaline earth methanolate as base. Y1 = H, 1-4C alkyl or phenyl, optionally substituted by 1-4C alkyl, alkoxy or halogen, or NR5R6; R1-R6 = H, COOX or X, provided that at least one of R1-R6 is COOX; X = 1-13C alkyl optionally containing 1-2 ether linkages; Y2 = H, 1-4C alkyl, amine or phenyl optionally substituted by 1-4C alkyl, alkoxy or halogen whereby when Y2 is not amine at least one of R1-R4 is H.
