Abstract

Abstract : 2, 6-bis(benzimidazol-2-yl)pyridines are more electron-rich yet more sterically open ligands for monovalent and trivalent group 13 elements than bis(imino)pyridines. Abstract : Treatment of GaCl3 with 2, 6-bis(benzimidazol-2-yl)pyridine (G-BZIMPY, G = NBz, N(3, 5-CF3 )Bz, N -allyl and O) yielded the autoionization products [G-BZIMPYGaCl2 ][GaCl4 ] (1–4 ) in great yields. The Ga(iii ) complex1 was reduced to Ga(i ) using K2 [Fe(CO)4 ], resulting in the complex [(NBzBZIMPY)(Cl)Ga–Fe(CO)4 ] (7 ). GaCl3 and AlCl3 were complexed by the structurally similar bis(imino)pyridine (DIMPY) and the resulting complexes are compared to those of G-BZIMPY.
