Synthesis of various derivatives of 2-(2-thienyl)pyridine via substituted 3-thienyl-1,2,4-triazines is reported. The final step of the synthesis is a transformation of the triazine ring to pyridine in an aza-Diels−Alder-type reaction. The resulting 5-aryl-2-(2-thienyl)pyridines (HL1-HL4) and 5-aryl-2-(2-thienyl)cyclopenteno[c]pyridines (HL5-HL8) (with aryl = phenyl, 4-methoxyphenyl, 2-naphtyl, and
据报道,通过取代的3-噻吩基-1,2,4-三嗪可合成2-(2-噻吩基)吡啶的各种衍生物。合成的最后一步是在aza-Diels-Alder型反应中将三嗪环转化为吡啶。所得的5-芳基-2-(2-噻吩基)吡啶(HL1-HL4)和5-芳基-2-(2-噻吩基)环戊烯并[ c ]吡啶(HL5-HL8)(芳基=苯基,4-甲氧基苯基,2-萘基和2-噻吩基)用作环金属配体,以制备一系列八种类型的发光铂络合物,类型为[Pt(L)(acac)](L =环金属配体,acac =乙酰丙酮基)。[Pt(L5)(acac)] = [Pt(5-苯基-2-(2-噻吩基)环戊烯[ c ]吡啶](acac)],[Pt]的三个配合物的X射线单晶结构(L6)(acac)] = [Pt(5-(4-甲氧基)-2-(2-噻吩基)环戊烯[c [吡啶](acac)],并确定[Pt(L7)(acac)] = [Pt(5-(2-萘基)-2-(2-噻吩基)环戊烯[
