α-Alkylated (dimethylsilyl)acetonitriles (Me2HSiCR3R4CN) react spontaneously with aldehydes in DMSO to give β-hydroxynitriles in good to high yields. The addition to ketones is effectively promoted by using MgCl2 or CaCl2. (Dimethylsilyl)acetonitrile (Me2HSiCH2CN) shows lower reactivity than the α-alkylated analogs. However, the parent reagent adds efficiently to aldehydes and ketones under catalysis by AcOLi or MgCl2.

Author is Feroci, M.; Orsini, M.; Sotgiu, G.; Inesi, A..

The electrochem. activation of organic solvents HS (CH3CN, CH3CH2CN, DMF, DMSO) containing Et4NPF6 as supporting electrolyte (i.e. their electrolysis under galvanostatic control) allows to induce in these solutions, in the absence of any catalyst, the Knoevenagel condensation between CH-acid CH2(CN)2 (1) and carbonylic substrates. Reaction products were isolated in good yields 97-48%. The progress of the Knoevenagel condensation is affected by Q (number of Faradays per mol of 1 supplied to the electrodes) and, moderately, by the nature of the solvents. The rates of the single steps are compared by elementary voltammetric anal.

Olefins conjugated with carbonyl, carboxylic ester, and Ph groups as well as highly strained non-conjugated olefin norbornylene were converted to their corresponding α-hydroxy-β-cyanoadducts by treatment with mercuric fulminate and lithium bromide. The transformation appears to go through a 1,3-dipolar cycloaddition of metal fulminate to the olefin followed by a spontaneous cleavage of the resulting heterocycle. Thus, the study provides the first one step cis-cyanohydroxylation of olefinic species.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 3-Hydroxy-3-phenylpropanenitrile(SMILESS: N#CCC(O)C1=CC=CC=C1,cas:17190-29-3) is researched.Related Products of 814-94-8. The article 《Ionization of an α-hydrogen of acetonitrile by n-butyllithium and alkali amides. Condensations with ketones and aldehydes to form β-hydroxynitriles》 in relation to this compound, is published in Journal of Organic Chemistry. Let’s take a look at the latest research on this compound (cas:17190-29-3).

MeCN underwent mainly ionization of an α-H with BuLi in tetrahydrofuran-hexane, rather than an addition reaction involving the CN group. The former course of reaction was evidenced by an addition of the resulting lithioacetonitrile to benzophenone (I), to form 89% 3-hydroxy-3,3-diphenylpropanonitrile. Similarly, an α-H of MeCN was ionized by Na, Li, and K amides in liquid NH3 and the resulting alkali acetonitrile condensed with I to give this β-hydroxynitrile in 93, 85, and 69% yields, resp. The BuLi method was extended to several other ketones and to BzH. These results illustrate convenient methods for the synthesis of such β-hydroxynitriles, which can be dehydrated with acid to form the corresponding unsaturated nitriles. 26 references.
