"PROCESS FOR THE PREPARATION OF COMPOUNDS OF FORMULA (V) IN THE FROM OF THE COMPOUND VA OR VB"

Abstract The present invention relates to a process for the preparation of a compound formula (V) in the form of the compound Va or Vb, wherein X represents O or NH, wherein acetic acid derivatives of the formula IXa or IXb are reacted with enamines of the formula (VIII).
Full Text The present invention relates to process for the preparation of compounds of the formula (V) in the form of the compound Va or Vb..
The invention relates to pyridone-methide azo dyestuffs, processes for their preparation, their use and coupling components containing pyridone-methide.
Azo dyestuffs which contain a coupling component based on methylene-triazolo-pyridines are already known from DE-A 4 020 768 and DE-A 4 329 296. However, these azo dyestuffs still have some disadvantages in their use. Thus, for example, their build-up capacity and their stability in the dyebath when used for dyeing polyester is not satisfactory. /
Pyridone-methide azo dyestuffs have now been found, which, in the form of the free acid, correspond to the formula (I) or its tautomeric forms
(Formula Removed)
wherein
D is the radical of a carbo- or heterocyclic diazo component,
A1 and A2 independently of one another denote H or a substituent typical for pyridones,
A-1 and A4 independently of one another denote an electron-withdrawing radical, or, together with the common C atom, form a cyclic methylene-active compound,
A3 represents H or a radical of the formula T, -OT1, -NH2, -NHT, -NT,, -NHCOH, -NHCOT, -N=CH-T, -N=CT2 or NHSO2T,
wherein
T = alkyl, cycloalkyl or aralkyl, and T represents T1 or can assume the meaning of T2 to T5 where T2 = alkenyl,
