The boron-mediated ketone-ketone aldol reaction
The first examples of the directed, boron-mediated aldol reaction between different ketones are presented. Transformation of a variety of ketones to their corresponding boron enolates with Chx2BCl/Et3N, followed by reaction with acceptor ketones in diethyl ether, and oxidation of the resultant boron aldolate (H2O2, MeOH/pH 7 buffer), provided the aldol addition products. The reaction was most f...
متن کاملMethyl ethyl ketone and methyl isobutyl ketone not carcinogenic.
Methyl Ethyl Ketone and Methyl Isobutyl Ketone Not Carcinogenic The April 22, 1993, issue of Environmental Health Perspectives contained a commentary by Legator and Strawn entitled "Public Health Policies Regarding Hazardous Waste Sites and Cigarette Smoking: An Argument by Analogy." Although the article does not include any discussion of either methyl ethyl ketone (MEK) or methyl isobutyl keto...
متن کاملThe chemisorption of H2C[Si(CH3)3]2 and Si6(CH3)12 on Si(100) surfaces
The chemisorption of bis~trimethylsilyl!methane ~BTM, CH2@Si~CH3!3#2! and dodecamethylcyclohexasilane ~DCS, Si6~CH3!12! on clean Si~100! surfaces has been studied by C 1s core-level and valence-band photoemission spectroscopy. Our model for the deposition of carbon by BTM involves decomposition into a –CH2Si~CH3!3 surface moiety for room-temperature adsorption, which further decomposes upon ann...
متن کاملNon-Covalent Interactions in Hydrogen Storage Materials LiN(CH3)2BH3 and KN(CH3)2BH3
In the present work, an in-depth, qualitative and quantitative description of non-covalent interactions in the hydrogen storage materials LiN(CH3)2BH3 and KN(CH3)2BH3 was performed by means of the charge and energy decomposition method (ETS-NOCV) as well as the Interacting Quantum Atoms (IQA) approach. It was determined that both crystals are stabilized by electrostatically dominated intraand i...
