A series of quaternary ammonium salts has been tested as phase transfer agents to promote reactions between phenols and alkyl halides in an aqueous solution of sodium hydroxide in the absence oforganic solvent. Methyltrioctylammonium chloride emerges as the most effective catalyst.

4-Methylenedioxy-l-(3-phenylpropionyl)benzene exhibits anti-inflammatory activity and has low toxicity [1]. Therefore, in order to study the relationship between chemical structure and pharmacological properties and to investigate novel pharmaceuticals, we have synthesized and studied some new structural analogs (IIa-d) of this ketone. 3,4-Polymethylenedioxy-l-(3-phenylpropionyl)benzenes IIa-d were synthesized by
