Application:	1,4-Dioxane may undergo nickel-catalyzed oxidative arylation with arylboronic acids to form α-arylated ethers. It may be used as a solvent to synthesize: • (Chloromethyl)dimethylphenylsilane from chloro(chloromethyl)dimethylsilane via zinc-catalyzed substitution reaction with phenylmagnesium bromide. • N-(2,2,2-trifluoro-1-hydroxyethyl)-acetamide from 2,2,2-trifluoro-1-methoxyethanol and acetamide.
Other Notes:	The article number 296309-4X2L will be discontinued. Please order the single bottle 296309-2L which is physically identical with the same exact specifications.
