Description

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.

Solvent Miscibility Table

Substances are said to be miscible in one another if they dissolve to form a uniform solution. Bookmark or download our miscibility table for common lab solvents.

Scale-Up Guide: Buchwald-Hartwig Amination

Preformed catalysts in the kit are stable but become air-sensitive when activated; Schlenk technique aids scale-up.
