Cohalogenation of alkenes in ethylene oxide: Efficient methodology for the preparation of allyl vinyl ether precursors of γ,δ-unsaturated aldehydes

An investigation of the cohalogenation-dehydrohalogenation sequence as a method for the preparation of allyl vinyl ethers from simple olefins has been performed. Alkenes 1a-k react with bromide or chloride in the presence of ethylene oxide at -80°C to for

PHOTOLYSIS OF THE AZOALKANE 2,3-DIAZATRICYCLO4,9>NON-2-ENE: DIRECT OBSERVATION OF 4-CYCLOHEXENYLDIAZOMETHANE

Besides denitrogenation to the tricycloalkane 8, the photolysis of azoalkane 3 affords the diazoalkane 4, which serves as precursor to the minor hydrocarbon products 9, 10 and 11; irradiation of azoalkane 3 with the 333.6 nm line of an 18-W argon ion laser was essential to obtain preparative quantities of diazoalkane 4 for its detection and identification.
