Potassium-graphite (C8K) reacts with weak protic acids such as water and alcohols predominantly by an acid-base reaction with only small amounts of hydrogen evolution to yield a partially reduced graphite as shown by E.S.C.A. spectroscopy.
This paper describes chemistry using organocatalysts in hydrocarbon solvents that minimizes solvent waste by using inexpensive, non-volatile, relatively inflammable, and easily recyclable poly(α-olefin)s (PAOs) as hydrocarbon solvents.
Organocopper® ate complexes can be prepared in high yield from methylcopper® and aliphatic or aryl Grignard reagents. The resulting complexes efficiently transfer the Grignard reagent derived primary, secondary, tertiary, or aryl group in reactions in acyl chlorides leading to ketones. This synthetic method is illustrated with procedures for CH3(CH2)i6COCH3, CeHBCOCeHB, CH3(CH2)2CH(CH3)COCH3, (CH3)3CCOC6H5, p-CH3C6H4COC6H5, C6H6COCH3, (CH3)3CCOC(CH3)3, and 06 00(0 2)30 3. This reaction provides a general and useful alternative to syntheses of organocopper® ate complexes from organolithium reagents. Methylcopper® is shown to be significantly better than other copper® species for forming reactive organocopper® ate complexes from Grignard reagents.
Polystyrene-bound anthracene has been prepared and found to react with sodium-naphthalene to give a polymeric radical anion whose chemistry is analogous to that of soluble alkali metal aromatic radical anions.
C8K, eine typische Alkalimetall‐Einlagerungsverbindung, unterwirft sich Reaktionen mit organischen Verbindungen durch Ein‐ und Zweielektronenprozessen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
