First structurally characterised metal complex of a 2H-benzimidazole derivative. Copper mediated synthesis of 2,2-dimethyl-2H-benzimidazole from 1,2-phenylenediamine and acetone
Abstract
2,2-Dimethyl-2H-benzimidazole (1) was synthesised by exploiting the reaction of acetone with bis(1,2-phenylenediamine)copper(II) perchlorate. Additionally, the X-ray crystal structure of [CuI(1)(PPh3)2]ClO4 is reported.
