Abstract

A series of novel vanadium (III) complexes bearing iminopyrrolide chelating ligands [2- (RNCH) C4H3N] V (THF) 2Cl2 (2a: R= cyclohexyl; 2b: R= Ph; 2c: R= 2, 6-iPr2C6H3; 2d: R= p-CF3C6H4; 2e: R= C6F5) have been synthesized and characterized. Single-crystal X-ray diffraction revealed that complexes 2a, 2c and 2e adopt an octahedral geometry around the vanadium center. In the presence of Et2AlCl as a co-catalyst, these complexes displayed ...
