Process for the preparation of azamethines and azamethines obtained thereby |
| abstract |
The invention relates to a process for the preparation of azamethines of the general formula 1 by condensation of compounds of general formula 2 with methylene-active compounds of general formula 3A / 3B according to the following reaction scheme in a solvent at a temperature between 60 and 120 ° C and then isolating the products. The invention also relates to new azamethines, in particular those with heterocyclic structural elements. Because of their properties, these azamethines are suitable for use as nonlinear-optical chromophoric building blocks. |
