| Abstract: | The 1,4 dialkoxynaphthalo 2,3 dinitriles were synthesized from 1,4 naphthoquinone by bromination, cyanation and O alkylation. The brominating agent were used instead of luquid bromine in bromination. Dodecyl trimethylammonium bromide (DTMAB) and polyethylene glycol (PEG) were use as phase transfer catalysts in bromination and cyanation respectively. The reaction conditions were optimized by orthogonal design experiments, and the yield of cyanation was up to 88.7%. |
