摘要:
The production of 3-monochloro and 3,6-dichloro derivatives of 2,4,5-trialkylbenzophenones by reaction of 2,4,5-trialkylbenzophenones with chlorine, and the new 3-monochloro-2,4,5-trialkylbenzophenones and 3,6-dichloro-2,4,5-trialkylbenzophenones themselves. The products are starting materials for the production of dyes and pesticides.
摘要:
Methine or azamethine dyes are prepared on the basis of pyridine dyes by condensing an oxime- or formyl-pyridine or its tautomeric form with 5-membered aromatic heterocycles.
