Amine alkanal oxime

One of the exciting results to come out of heterogeneous catalysis research since the early 1980s is the discovery and development of catalysts that employ hydrogen peroxide to selectively oxidize organic compounds at low temperatures in the liquid phase. These catalysts are based on titanium, and the important discovery was a way to isolate titanium in framework locations of the inner cavities of zeolites (molecular sieves). Thus, mild oxidations may be run in water or water-soluble solvents. Practicing organic chemists now have a way to catalytically oxidize benzene to phenols alkanes to alcohols and ketones primary alcohols to aldehydes, acids, esters, and acetals secondary alcohols to ketones primary amines to oximes secondary amines to hydroxyl-amines and tertiary amines to amine oxides. [Pg.229]

Bei der Reduktion von Aldehyden und Ketonen werden neben den Alkoholen auch Di- und Polysulfane er-halten (s. S. 276), mit aromatischen Nitrilen im UberschuB5, mit Oxiranen (S. 422) und mit Thiiranen (S. 449) werden Thioamide, Dihydroxy-disulfane oder Polysulfane gebildet. Mit Thiolen entstehen Borsaure-trithioester, die mit Aldehyden und Ketonen Thioacetale ergeben6. Prim. Nitro-alkane Iiefern Nitrile, sek. Ketone und Oxime (S. 472), Nitro-aromaten die entspreehenden Amine (S. 478). Oxime konnen selektiv zu Hydroxylaminen Oder weiter zu Aminen reduziert werden (S. 375). [Pg.22]

Unlike many other type of radical addition reactions, the product is most often an alkyl-cobalt(III) species capable of further manipulation. These product Co—C bonds have been converted in good yields to carbon-oxygen (alcohol, acetate), carbon-nitrogen (oxime, amine), carbon-halogen, carbon-sulfur (sulfide, sulfinic acid) and carbon-selenium bonds (equations 179 and 180)354. Exceptions to this rule are the intermolecular additions to electron-deficient olefins, in which the putative organocobalt(III) species eliminates to form an a,/ -unsaturated carbonyl compound or styrene353 or is reduced (under electrochemical conditions) to the alkane (equation 181)355. [Pg.1330]

Cathodic reduction consists of electron supply from the cathode, followed by acquisition of protons by anionically charged substrates. Thus, ready accessibility of the reductive electron transfer processes leads to a variety of reactions, including reductive abstraction of halogens [13, 14], reduction of alcohols to alkanes [15], reduction of imines, oximes, and hydrazones to the corresponding amines [16], and conversion of nitro groups to the corresponding nitroso, hydroxy amino, and amino groups [17].

Treatment of primary aromatic amines with Ph3PBr2 to produce the imino-phosphorane followed by addition of an alkyl iodide provides a convenient monoalkylation procedure.The reagent system BusP-CCU-KCN-lS-crown-6 effects a simple one-pot conversion of primary alcohols to nitriles. Finally, PI3 deoxygenates sulphoxides, selenoxides, aldehyde oximes, and nitro-alkanes, and deprotects acetals and ketals. ... [Pg.249]
