Several good methods are known for the monodealkylation of quaternary ammonium compounds employing non-reductive nucleophilic agents (l-5). We wish to report here a simple one-step method that leads directly from a quaternary ammonium salt to the acyl derivative of the corresponding secondary amine

Six organometallic compounds were tested to see if they could behave as phase Summary: transfer catalysts. All of the compounds appeared to catalyze the base hydrolysis of p-nitrophenylacetate in a 2 layer aqueous-organic system. Research on phase transfer catalysis (PTC) has largely been focused on
