    • Abstract


      1. Malonanilic acid has been condensed with several aromatic aldehydes and a comparative study is made of the yields obtained by (i) the method of using pyridine in large excess together with a trace of piperidine and (ii) the method of using only a trace ofeither of the two.

      2. The yields obtained by applying method (i) as Ahluwalia, Haq and Ray have done, are increased further by some modifications adopted in his paper. But even the highest yields so obtained, are lower than those obtained by the application of methods (ii).

      3. Incidentally, therefore, the utility of method (ii), observed in condensations of aldehydes with malonic acid, is thus extended further.
