Quinone diazides and enaminones as a source of new azo compounds with potential nonlinear optical properties

摘要

Quinone diazides are compounds that have intermedi- ate reactivity between diazonium salts and aliphatic diazo ketones. They can react by either loss or retention of molecular nitrogen, depending on reaction conditions. An example of the first case involves the formation of Dihydrobenzofurans by a regiospecific route in reactions Of o-quinone diazides with vinyl ether under thermal Conditions.
