  • the products of Formula If can be isolated by evaporation of the solvent, and dissolving the residue in a water-immiscible solvent such as methylene chloride. This solution may be washed with dilute aqueous mineral acid, water, brine, and dried. Evaporation of the solvent followed by crystallization or chromatography affords the products of Formula If.
  • alkyl, alkenyl, and alkynyl radicals are the normal isomers.
  • reaction solution was stirred at room temperature overnight and was then added to water (20 mL).
