• Widely used phase-transfer catalyst; see Appendix 2. Some illustrative applications are given below:
• 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).
• 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).
