SYNTHESIS OF SOME POTENTIAL SEMI-CONDUCTOR COMPOUNDS VIA ARYLATION OF BENZO[1,2-b:4,5-b’]DITHIOPHENE

Tóm tắt

Four potential semiconductors containing benzo[1,2-b:4,5-b’]dithiophene were successfully
synthesized via Heck-type coupling reaction. The best condition of the arylation was optimized. The
selectivity of the first and second arylation at positions 9 and 10 were elucidated with HMBC spectrum
and X-ray analysis.
