Abstract
Carbocyanine dyes, having a substituent in the carbocyanine chain are produced by treating two molecular proportions of a quaternary salt of a heterocyclic nitrogenous base having an active a -methyl group with at least two molecular proportions of an organic carboxylic acid anhydride, in the presence of not more than one molecular proportion of an acid-binding substance, e.g. the salt of a weak acid. If acetic anhydride is used as the acid anhydride, an a -acetylmethyl derivative of the quaternary salt is first formed, with liberation of a molecule of acetic acid, and a second molecule of the quaternary salt then condenses with the acetyl derivative, a further molecule of acetic anhydride being used as a dehydrating agent, and the acid-binding substance removing one molecule of the hydriodic or other acid of the quaternary salt. According to examples, (1) acetic anhydride is condensed with 1-methylbenzthiazole ethiodide, 2 : 3 : 3-trimethylindolenine ethiodide, quinaldine ethiodide, 1-methylbenzoxazole ethiodide, 1-methyl-3 : 4-benzbenzthiazole ethiodide and 1-methyl-5 : 6 - benzbenzthiazole ethiode, by heating under reflux in the presence of anhydrous sodium acetate: (2) 1-methylbenzoxazole ethiodide is similarly condensed with benzoic anhydride: (3) 1-methylbenzthiazole ethiodide is condensed with acetic anhydride in the presence of sodium formate. Sodium salicylate is also mentioned as an acid-binding agent, and propionic anhydride as a suitable anhydride. Many of the products are photographic sensitizers. Specification 232,740, [Class 2 (iii), Dyes &c.], is referred to. According to the Provisional Specification, acid anhydrides may be condensed with quaternary salts of heterocyclic nitrogenous bases having either a reactive hydrogen atom or methyl group in the a or g positions. For example, benzthiazole ethiodide may be condensed with acetic anhydride. Quinoline and lepidine are also mentioned as suitable bases whose quaternary salts may be used.
