Comparison of the rates of displacement of F- in 1-fluoro-2- or 4-nitrobenzene with KOMe and KO-t-Bu in the presence of this crown ether gave a result (t-BuO- >> MeO-) opposite to the pattern observed in its absence: J. Chem. Soc., Perkin 2, 55 (1973). Promotes the generation of bromochlorocarbene from Chlorodibromomethane: Syntheis, 783 (1977); Tetrahedron, 33, 363 (1977), and of dibromocarbene from Bromoform: Org. Synth., 75, 98 (1997). In combination with Benzyl-triethyl-ammonium chloride, promotes the oxidative decarboxylation of arylacetic acids with NaIO4 to give high yields of the aryl aldehydes: Indian J. Chem. B, 35B, 151 (1996). Catalyst for the formation of phenacyl esters from phenacyl bromides and K salts of carboxylic acids in acetonitrile: Synth. Commun., 26, 1747 (1996). Catalyst for the halogenative cleavage of epoxides with Br2 or I2, giving halohydrins in high yields: J. Org. Chem., 63, 1455 (1998).
