The coordination chemistry of four enantiopure tetradentate bis(iminoquinoline) ligands with nickel(II) salts is reported. The previously reported ligands CBQ, CPQ, BBQ, and BPQ result from the condensation of (1R,2R)-cyclohexyldiamine or (R)-BINAM with two equivalents of 2-formylbenzo[h]quinoline or 8-isopropyl-2-quinolinecarboxaldehyde CBQ = (1R,2R)-cyclohexanediamine-N,N′-bis(benzo[h]quinoline-2-ylmethylene)
报道了四个对映纯四齿双(亚氨基喹啉)配体与镍(II)盐的配位化学。先前报道的配体CBQ,CPQ,BBQ和BPQ是由(1 R,2 R)-环己基二胺或(R)-BINAM与两个当量的2-甲酰基苯并[ h ]喹啉 或者 8-异丙基-2-喹啉甲醛CBQ =(1 R,2 R)-环己二胺-N,N'-双(苯并[ h ]喹啉-2-基亚甲基),CPQ =(1 R,2 R)-环己二胺-N,N'-双[ [(8-异丙基)-2-喹啉基]亚甲基],BBQ = [(R)-1,1'-联萘] -2,2'-二胺-N,N'-双(苯并[ h ]喹啉-2 -(亚甲基),BPQ = [(R)-1,1'-双萘] -2,2'-二胺-N,N'-双[[(8-异丙基)-2-喹啉基]亚甲基]}。NiI 2与(1 R,2R)-环己基配体给出了单核变形的三角双锥体(TBP)配合物[Ni(N 3 -CBQ)I 2 ]和[Ni(N 3 -CPQ)I 2
