N,N-Diaryl-substituted 2-aminothiophenes 3 have been transformed by reaction with several bromobenzenes 5 and 2-bromothiophenes 6 in a palladium catalysed cross-coupling reaction, via 2-(N,N-diarylamino)-5-stannyl-thiophenes 4, into N,N-diaryl-substituted 2-amino-5-phenylthiophenes 7 and 5-amino-2,2′-bithiophenes 9 as well as into N,N′-peraryl-substituted 5,5′-diamino-2,2′-bithiophenes 8 and their phenylene and thienylene homologues 10-13.
N,N-二芳基取代的2-氨基噻吩3通过与几种溴苯5和2-溴噻吩6在钯催化下的交叉偶联反应,经由2-(N,N-二芳基氨基)-5-锡基噻吩4,被转化为N,N-二芳基取代的2-氨基-5-苯基噻吩7和5-氨基-2,2'-联噻吩9,以及转化为N,N'-全芳基取代的5,5'-二氨基-2,2'-联噻吩8及其苯ylene和噻吩ylene类似物10-13。
