2-mercaptoacetate led to the formation of ethyl 3-decyl-2,2':5',2'':5'',2'''-quaterthiophene-5- and 5-(biphenyl-4-yl)-4-decylthiophene-2-carboxylates, which are of interest as building blocks for the synthesis of organic semiconductors. Ethyl 3-decyl-2,2':5',2'':5'',2'''-quaterthiophene-5-carboxylate was also obtained by palladium-catalyzed cross coupling of ethyl 5'-bromo-3-decyl-2,2'-bithiophene-5-carboxylate with
2,2':5',2''-对噻吩和联苯的酰化反应产生1-(2,2':5',2''-对噻吩-5-基)十二烷基-1-酮和1-(联苯- 4-基)十二烷基-1-酮,将其用氯氧化磷和二甲基甲酰胺处理后转化为2-[((2,2':5',2''-对噻吩-5-基)-氯亚甲基]十二烷基醛和2- [(联苯基-4-基)氯亚甲基]十二烷基。这些化合物与2-巯基乙酸乙酯的反应导致形成乙基3-癸基-2,2':5',2'':5'',2'''-四噻吩-5-和5-(联苯) -4-基)-4-癸基噻吩-2-羧酸盐,作为有机半导体合成的基础材料而受到关注。3-癸基乙基-2,2':5',2'':5'',2'''
