The present invention generally relates to compositions and methods for inhibiting corrosion at a surface in the production, transportation, storage, and separation of crude oil and natural gas. 2. (canceled)4. An anti-corrosion composition comprising the compound of formula (I) claim 3 , (II) claim 3 , (III) or (IV) of .5. The method of claim 1 , wherein the anti-corrosion composition comprises the compound of formula (I).8. (canceled)9. The method of claim 1 , wherein Rof Formula (I) claim 1 , (IA) or (IB) is either:{'sub': 1', '24', '1', '24', '6', '12', '3', '8', '2', '2', '1', '6', '1', '6', '2', '10', '11', '2', '10', '11', '1', '6', '2', '1, 'C-Calkyl, C-Calkenyl, C-Caryl, monocyclic or bicyclic heteroaryl, or C-Ccycloalkyl, wherein said alkyl, alkenyl, aryl, heteroaryl, or cycloalkyl are each independently unsubstituted or substituted with 1 to 3 substituents independently selected from —F, —Cl, —NO, —CN, —OH, —NH, C-Chaloalkyl, C-Calkoxy, —COR, and —CON(R), wherein Rand R, at each occurrence, are each independently hydrogen or C-Calkyl; or optionally one or more of the —CH— groups of Ris replaced with a —C(O)O— group; or'}{'sub': 1', '18', '3', '8', '1', '6', '2', '10', '10', '1', '6', '2', '1, 'C-Calkyl, or C-Ccycloalkyl, wherein said alkyl, or cycloalkyl are each independently unsubstituted or substituted with 1 to 3 substituents independently selected from —OH, C-Calkoxy, or —CORwherein Rat each occurrence, is independently hydrogen or C-Calkyl; or optionally one or more of the —CH— groups of Ris replaced with a —C(O)O— group.'}10. (canceled)11.
