A process for the preparation of a polycyclic dye of Formula I:
by reacting a phenyltartronic acid of Formula II:
wherein
W is - NR¹R² or - OR³;
R³ is H or an optionally substituted alkyl, alkenyl, cycloalkyl or aralkyl group;
R¹ & R² are each independently H or an optionally substituted alkyl, alkenyl, cycloalkyl, aralkyl or aryl group; or
R¹ & R² together with the nitrogen atom to which they are attached form a heterocyclic ring; or
R¹ or R² together with the nitrogen atom and the adjacent carbon atom of Ring B form a heterocyclic ring; and
Ring B is unsubstituted, apart from the group W, or is substituted by one or two further groups;
with either (a) a compound of Formula III:
wherein,
Z¹ & Z² are each independently - O -, - S - or - NY - in which Y is H, an optionally-substituted hydrocarbon group or an acyl group;
X¹ & X² are each independently selected from H, halogen, cyano, alkyl, aryl, carbamoyl, sulphamoyl, COOH and carboxylic acid ester; &
Ring A is unsubstituted or is substituted by from one to three groups;
or (b) a compound of Formula IV:
wherein Z¹, Z², X¹ and X² are as hereinbefore defined;
and oxidation of the intermediate compound to dehydrogenate the peripheral heterocyclic rings.
The invention also comprises a product of the aforementioned process which is suitable for the colouration of polyester textile material in shades from green through to reddish-blue of the formula:
wherein:
X¹ & X² each independently is H, cyano, alkyl, aryl, carbamoyl, sulphamoyl, COOH or carboxylic acid ester;
Z¹ & Z² each independently is - O -, - S - or - NY - in which Y is H, an optionally-substituted hydrocarbon group or an acyl group;
R¹ & R² each independently is H or an optionally substituted alkyl, alkenyl, cycloalkyl, aryl or aralkyl group; or
R¹ & R² together with the N atom to which they are attached, form a heterocycle;
R⁴ & R⁵ each independently is H, halogen or an optionally substituted alkyl, alkenyl or alkoxy group; or
R¹ & R⁴ together with the N atom and the two carbon atoms in Ring B to which they are attached form a heterocycle fused to Ring B; or
R² & R⁵ together with the N atom and the two carbon atoms in Ring B to which they are attached form a heterocycle fused to Ring B;
R⁶ is H, halogen, an optionally substituted alkyl or alkoxy group or a group NR¹R² in which each of R¹ and R² independently is as hereinbefore defined;
R⁷ & R⁸ each independently is H, halogen or an optionally substituted alkyl, alkenyl or alkoxy group; or
R¹ & R⁷ together with the N atom and the two carbon atoms in Ring A to which they are attached form a heterocycle fused to Ring A; or
R² & R⁸ together with the N atom and the two carbon atoms in Ring A to which they are attached form a heterocycle fused to Ring A;
and where R⁶ is NR¹R², this may be the same as or different from the NR¹R² group present in Ring B.
