Induced halogenation of alkyl cyclohexenyl ketones involving metal halides, hydrohalogenic acids, and hydrogen peroxide
摘要:
The induced halogenation and hydroxyhalogenation of alkyl cyclohexenyl ketones in a system [MHlg + HHlg or HHlg]-H(2)O(2) or in NaOCl was performed and optimum reaction conditions were established. Under mild conditions the electrophilic addition of the halogen or the acid occurred at the multiple bond of the ring with the formation of the corresponding dihalo or hydroxyhalo derivatives of cycloaliphatic ketones. From the compounds obtained epoxy- and dioxyketones of aliphatic series were prepared. Chloro(bromo)hydrins of ketones from the alkylcyclohexane series and oxiranes based thereon are reactive compounds and can be employed as synthons in the organic synthesis.

An ink composition is provided that includes a cationically polymerizable compound (a), a compound (b) that generates an acid when exposed to radiation, a colorant (c), and a salt of a weak acid having a pKa of 4 to 8 (d). There is also provided an inkjet recording method that includes a step of discharging the ink composition onto a recording medium, and a step of irradiating the discharged ink composition with radiation so as to cure the ink composition.
Friedel-Crafts-type acylation of alkenes with acyl chlorides has been successfully conducted with a wide substrate scope by the combined use of AlCl3 and 2,6-dibromopyridine. Trisubstituted alkenes afford allylketones or vinylketones depending on the presence or absence of hydrogen atom(s) at the beta-position to the acylation site, while monosubstituted alkenes exclusively afford vinylketones.
