Methods for preparing alkenylphenone corrosion inhibiting compositions may include providing an arylacetone and reacting the arylacetone with formaldehyde in the presence of a strong base catalyst. Corrosion inhibiting compositions may include an alkenylphenone, which may be prepared by a method including providing an arylacetone and reacting the arylacetone with formaldehyde in the presence of a strong base catalyst. Methods of inhibiting corrosion of a steel surface of an oilfield equipment component may include contacting the steel surface with an aqueous solution comprising a corrosion inhibitor. The corrosion inhibitor may include a composition containing an alkenylphenone prepared by reacting an arylacetone with formaldehyde in the presence of a strong base catalyst.
