где Аг - фенил, п - метоксифенил или отирил, которые наход т широкое применение в фотографической промышленности в качестве сенсибилизаторов.where Ar is phenyl, p is methoxyphenyl or otiril, which are widely used in the photographic industry as sensitizers.
Известен способ получени соединений Недостатками этого способа вл ютс 5 трудность выделени целевого продукта, так как он получаетс в смеси с солью Known method of producing compounds. The disadvantages of this method are 5 difficulty of extracting the target product, as it is obtained in a mixture with salt.
общей формулы I, заключающийс в том, что соль 2,4,6-триметнлпирили подвергают взаимодействию с ароматическим альдегидом общей формулы IIGeneral formula I, namely, that the salt of 2,4,6-trimetnylpyryl is subjected to interaction with an aromatic aldehyde of the general formula II
