설명

애플리케이션

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.
