Benzanilides have been N-alkylated in the presence of NaOH and K2CO3: Synth. Commun., 18, 2011 (1988).
It was the most effective catalyst studied for the cyclization of ?-amino acids to ?-lactams by methanesulfonyl chloride and KHCO3: Chem. Lett., 443 (1981).
In the dehydrohalogenation of aryl 2-haloethyl ethers to give vinyl ethers, this catalyst was found much more effective than the corresponding halides or benzyltriethylammonium salts: Synthesis, 688 (1979).
The oxidation of primary alcohols to aldehydes by potassium chromate under phase-transfer conditions is better for higher homologues, where solubility in the aqueous phase is limited: Synthesis, 134 (1979). For phase-transfer catalyzed dichromate oxidation of secondary alcohols to ketones, see: Tetrahedron Lett., 1601 (1978).
