  • halogen
  • PREPARATION: A compound (e.g., 2-amino-6-trifluoromethylbenzothiazole) shown by the formula II is reacted with a compound (e.g., 2,6-difluorobenzoyl chloride) shown by the formula III (Hal is halogen), to give a compound shown by the formula I. (google.com)
  • novel
  • Oligomerized in this fashion, the novel compositions possess azlactone groups which can be reacted with nucleophiles in the normal ring-opening sense. (google.com)
  • diethyl
  • Usually, these modifications are based on using dehydration reagents such as K 2 CO 3 , CaO, p-toluenesulfonic acid (TsOH), boron trifluoride diethyl etherate (BF 3 -OEt 2 ), acetic acid (AcOH), magnesium sulfate (MgSO 4 ), calcium hydride (CaH 2 ), titanium tetrachloride (TiCl 4 ), and molecular sieves (see J. Kang above). (google.com)
  • example
  • For this purpose it is preferred to use those compounds which contain a p-alkoxy group in addition to the o-hydroxy group, which alkoxy group may also be substituted, as taught, for example, in U.S. Pat. (google.com)
  • Methyl acrylate (in which Z=CO 2 CH 3 ), for example, polymerizes efficiently by radical and anionic initiation, but essentially not at all by cationic means. (google.com)

  • high
  • This drying and the solvent exchange on an industrial scale cost energy and are very time-consuming since if the compounds are dried too rapidly at excessively high temperatures, the pure product that is produced has a lower solubility in the oils usually used in cosmetics. (google.com)
