Disclosed herein is a first example of effective direct position specific C—H arylation of thieno[3,4-b]pyrazine derivative and several hetero aryl bromide under the ‘Heck-type’ experiment condition using Pd(OAc)

/n-Bu4NBr as a catalyst system, thienopyrazine in which aryl is replaced to increase various values. The current synthesis methodology is a simpler method than a facial method and is used to prepare π-conjugated oligomer and/or polymer material based on interesting hexylthiophen and thienopyrazine portion for electronic industries which construct a new synthetic organic material using potential application programs. The arylation generates more position selectivity in a C—H bond than in a pyrazine C—H bond. The optical and electrical characteristics of the synthesis copolymer are survey.
