A convenient synthesis has been achieved of 11 substituted phthalazines starting from the condensation of 2-( p-toluoyl)benzoic acid with hydrazine and some of its simple congeners, H2NNHR. Four of the phthalazines showed activity as inhibitors of the corrosion of steel immersed in 5 M HCl solutions.
