GB908352A - Substituted 1:3:5-triazines - Google Patents

Abstract

In the Provisional Specification reference is made to the preparation of 1,3,5-triazines which contain, attached to the carbon atoms of the triazine ring, at least one chlorine or bromine atom and at least one thiosulphate group by treating a triazine carrying at least two chlorine or bromine atoms with a thiosulphate. Specifications 363,690 and 885,059 are referred to.ALSO:The invention comprises 1,3,5-triazines which contain, attached to the carbon atoms of the triazine ring, at least one chlorine or bromine atom and at least one <FORM:0908352/IV (b)/1> wherein R1 represents a substituted or unsubstituted hydrocarbon or heterocyclic radical, R11 represents hydrogen or a substituted or unsubstituted hydrocarbon or heterocyclic radical, or, in the case wherein R1 and R11 are both attached to the same nitrogen atom, R1 and R11 may together with the nitrogen atom form a heterocyclic ring, X represents a carboxylic acid or ester group, and W represents a group of non-metallic atoms which together with the carbon atom form a 5- or 6-membered heterocyclic ring which may carry substituents or form part of a condensed ring system. When the compounds contain only one chlorine or bromine substituent and only one of the above groups, the third ring carbon atom may carry another substituent, many being specified. The compounds are prepared by treating a triazine carrying at least 2 chlorine or bromine atoms with a compound D-B wherein D is hydrogen or a metal (e.g. alkali metal) atom and B is one of the above groups, e.g. in aqueous or aqueous/organic solution or suspension at -20 to +100 DEG C. while maintaining the pH between 4 and 10 by addition of a base. When using trihalotriazines, one halogen may be replaced at -20 to +30 DEG C. and the second at 30-80 DEG C., or both at 30-80 DEG C. The products may be isolated and/or dried in the presence of a buffering agent. In addition to the above subject matter, the Provisional Specification refers to triazines containing at least one chlorine or bromine atom and at least one <FORM:0908352/IV (b)/2> <FORM:0908352/IV (b)/3> <FORM:0908352/IV (b)/4> group wherein R1 and R11 are as above, A1 and A11 each represent a hydrogen atom or hydrocarbon group, n and m are each 1 or 2, and X is chlorine or bromine. The Provisional Specification also refers to preparing the compounds containing the <FORM:0908352/IV (b)/5> group by oxidising the corresponding -SR1 compounds, e.g. with perbenzoic acid, and also to preparing triazines containing one chlorine or bromine atom, one of the above groups and one mercapto, hydroxy, amino or alkyl- or aryl-substituted mercapto, hydroxy or amino group by reacting a triazine with two chlorine or bromine atoms with D-Q where Q is a mercapto, hydroxy or amino, or substituted mercapto, hydroxy or amino group. Specifications 363,690 and 885,059 are referred to.
