Cascade reactions of amidines with nitroallylic acetates and α-bromonitroalkenes provide potentially bioactive imidazoles in good to excellent yields in most cases. While 2,4-disubstituted imidazol-5-yl acetates are formed in the first case, 2,4-disubstituted imidazoles, bearing no substituent at position 5, are the products in the second case. These two series of imidazoles, viz. 2,4,5-trisubstituted

A surface treating agent containing a novel phenylnaphthylimidazole compound represented by the following formula is brought into contact with the surface of copper or a copper alloy.
In the formula, when A
1
is a phenyl group, then A
2
represents a 1-naphthyl group or a 2-naphthyl group, and when A
1
is a 1-naphthyl group or a 2-naphthyl group, then A
2
represents a phenyl group; and R represents a hydrogen atom or a methyl group.
