    Abstract: 1,256,386. 1,3,5-Triazine derivatives. BADISCHE ANILIN- & SODA-FABRIK A.G. 3 April, 1969 [6 April, 1968], No. 17484/69. Heading C2C. Compounds of formula wherein R 1 is an aliphatic, cycloaliphatic, araliphatic or aromatic radical, and R 2 is an amino group or SR 1 , are prepared by reacting R 1 SC( :NH)NHC( :NH)R 2 (II) with R 4 OCH:NR 3 (III) or [R 4 OCH :NR 3 R 5 ] + X - (IV) wherein R 3 is H or R 1 , R 4 is an aliphatic radical, R 5 is H or an aliphatic radical and X is an acid radical. II may be formed in situ from an alkylating agent with a mono-S-substituted or S-unsubstituted dithioburet or unsubstituted guanidinothiourea. III or IV may be formed in situ from an alkylating agent with N-monoalkyl, N- dialkyl or unsubstituted formamide, or from an alkanol with a formamide chloride. Examples describe the preparation of 2,4-bis(methylmercapto)- and 2 - amino - 4 - methylmercaptos-triazines.
