Alumina chloral

A modified Oppenauer oxidation, using activated neutral chromatographic alumina and chloral in CCI4 at room temperature, allows the oxidation of cyclobutanol in ... [Pg.262]

Chloral is used as the hydrogen acceptor in the quantitative oxidation of cyclobutanol to cyclobutanone. The reaction takes place on Woelm alumina at room temperature in carbon tetrachloride after 24 h [95S]. Under similar conditions, primary alcohols are oxidized in preference to secondary alcohols [959]. [Pg.143]

On the other hand, secondary 3-hydroxy sulfides yield 3-keto sulfides on treatment with chloral on alumina (equation 577) [960. This result is understandable because dehydrogenation, and not true oxidation, is involved. [Pg.261]

Lithium or copper enolates, generated in situ by conjugate reduction of afi-unsaturated ketones, may be trapped by MeSSMe, PhSSPh, or PhSCl to give the /S-ketosulphide. /3-Keto-sulphides and -selenides are available on chloral-alumina oxidation of the corresponding /3-hydroxy compounds. The latter compounds may be prepared by alumina-promoted epoxide ring opening by thiols and selenols (Scheme 16). ... [Pg.35]
