Article abstract of DOI:10.1002/prac.199733901132

The cycloacylation reaction of benzamidines with bis-imidoylchlorides 1 derived from oxalic acid was investigated. For example, treatment of benzamidine with 1 gives the new 4H-imidazoles (3a-1) in yields up to 92%. Because of rapid H-transfer processes i
