Abstract
The invention comprises triazaindolizine compounds of formulae <FORM:0874204/IV (b)/1> or <FORM:0874204/IV (b)/2> or tautomers thereof, where R1 is hydrogen or a mercapto, alkythio or aralkylthio group (but not hydrogen in the second formula), R2 is hydrogen, alkyl, aralkyl, aryl or heterocyclic, R3 is hydrogen, alkyl or aralkyl, or R2 and R3 together make up the residue of an alicyclic or benzene ring. Compounds wherein R1 is mercapto may be prepared by reacting CS2 with a compound of formula <FORM:0874204/IV (b)/3> in the presence of a secondary or tertiary organic base and an alcohol as diluent. Compounds in which R1 is alkylthio or aralkylthio may be obtained by treating the corresponding alkali metal mercaptide with a molecular equivalent of an alkylating or aralkylating agent. Compounds of the first formula in which R1 is hydrogen may be prepared by the catalytic reduction of the corresponding mercapto compound with a Raney nickel catalyst containing adsorbed hydrogen. Compounds of the first formula given above wherein R1 is hydrogen and R2 and R3 together make up the residue of a benzene ring may be prepared by the reaction of formic acid (or, according to the first Provisional Specification, an anhydride of an aliphatic or aromatic carboxylic acid) with a compound of formula <FORM:0874204/IV (b)/4> Compounds of the first formula given above wherein R1 is alkylthio or aralkylthio may be obtained by heating to a temperature above its melting point a compound of formula <FORM:0874204/IV (b)/5> where R4 is alkyl or aralkyl; these compounds, when boiled in glacial acetic acid, yield compounds of the first formula given above (R1 being alkylthio or aralkylthio). According to the first Provisional Specification, when R2 and R3 together make up a benzene residue, R1 may also be alkyl, aralkyl or aryl; these values for R1 do not appear in the Complete Specification; these compounds may be prepared by reacting 2-hydrazino-4-hydroxyquinoazoline with formic acid or an anhydride of an aliphatic or aromatic carboxylic acid; and an additional example is given. The triethylamine salt of 2-(4-methyl-6-hydroxy-2-pyrimidyl)-dithiocarbazinic acid is obtained as a by-product when reacting 4-methyl-6-hydroxy-2-pyrimidylhydrazine with CS2, methanol and triethylamine. It is methylated with methyl iodide to yield 4-methyl-6-hydroxy-2[bis(methylthio)methylene hydrazino] -pyrimidine. The compounds of the invention are used in photographic silver halide emulsions (see Group XX). Specifications 851,815 and 851,816 are referred to.
