The a-(2\_arylhydrazino)-esters 1 react with i-propylmagnesium iodide to furnish 2-aryl-1,2-diazetidin-3-ones 2, which-in turn undergo ring-opening with methyllithium affording a-(2-arylhydrazino)-ketones 3. As part of a program to study a-(2-arylhydrazino)-alkanone arylhydrazonesl the synthesis of
