Compounds of formula T are prepared by heating a nitrile of the formula with a nitrile of the formula RjCN, bromo acetic ester and zinc in an inert organic solvent, preferably in an aromatic hydrocarbon, for example benzene, toluene, xylene.
Preferably, the reaction is carried out in two stages. In the first stage, to a suspension of zinc dust in an organic solvent activated by copper, a mixture of bromoacetic ester, nitramyl and zinc dust is added without air access. Then, heating i for a short time and then, as appropriate, by heating the air for a longer time. The compound of formula 1 can be isolated by filtration.
Depending on the type of substituents and polymers to be colored, the compounds of formula I can be used as soluble in. polymer dyes and, preferably, as pigments. In the latter case, it is advisable to convert the products obtained during the synthesis into a finely dispersed form. It is possible to do this in various known ways.
It is advisable to further treat the pigments with an organic solvent, preferably one that boils above 100 ° C.
Pigments have a BET 5-150 specific surface area.
