-
Paragraph 0025; 0036, (2018/07/10)
The invention will be benzo triazole structure and connected with the carbodiimide structure, to provide a molecular weight, the lower the melting point of the traditional single-carbodiimide high anti-ultraviolet type single-carbonization two imine compound, to overcome the traditional single-carbodiimide under the high temperature easily from the polyester, polyamino compounds to the disadvantages in the migration, improving the material water-resistant xie kang aging performance. The invention synthetic anti-ultraviolet type single-carbodiimide compound can be used as an anti-hydrolysis stabilizing agent for the polyurethane and polyester elastomer, and in particular can be used for photovoltaic industry, biodegradable material and the like.

During the diazo-coupling reaction, nucleophilic displacement of a nitro group was also observed. This was the main reaction (1→7) when the starting amine bore either a chlorine or methoxy group at the para position (1b-c). The newly prepared compounds (7) might serve as convenient building blocks in synthesis of some heterocycles. Versita Warsaw and Springer-Verlag Wien 2010.
