Di-n-heptyloxyazoxybenzene [2635-26-9] M 426.6, m 75 , 95 (smectic nematic) and 127 (nematic - liquid), pK j —5. Purified by chromatography on AI2O3 (" benzene), recrystd from hexane or 95% EtOH and dried by heating under vacuum. The liquid crystals can be sublimed in vacuo. [Mellifiori et al. Spectrochim Acta Part A 37(A) 605 1981 Dewar and Schroeder J Am Chem Soc 86 5235 1964-, Weygand and Glaber J Prakt Chem 155 332 1940]. [Pg.206]

The first synthesis of a 3,5-diarylisoxazole from aryl hydroxamic acid chlorides and sodium phenyl acetylides was that effected by Weygand and Bauer in 1927. Beginning in 1946, when Quilico and Speroni showed that acid chlorides of hydroxamic acids on treatment with alkalies readily yielded nitrile oxides,numerous isoxazole and especially A -isoxazoline derivatives have been prepared. [Pg.373]
