摘要:
Described are methods for preparing a deuterated aldehyde using with a photocatalyst and a hydrogen atom transfer agent in a H2O free solvent comprising D2O and an organic solvent under an inert gas. The methods may be used to convert a wide variety of aldehydes (e.g., aryl, alkyl, or alkenyl aldehydes) to C-1 deuterated aldehydes under mild reaction conditions.

The invention provides for directing an oxygenate-contaminated propylene-containing stream derived from an oxygenate to olefin reaction system to a derivative non-polymerization reactor for conversion of the propylene to one or more derivative non-polymerization products. Exemplary derivative non-polymerization propylene conversion processes include: oxidation to form acrolein, oxidation to form acrylic acid, ammoxidation to form acrylonitrile, liquid phase oxidation to form acetone, liquid phase hydration to form isopropanol, hydroformylation to form n-butyraldehyde and its subsequent aldol/hydrogenation to form 2-ethylhexanol, direct or indirect oxidation to form propylene oxide, alkylation to form cumene in the presence of phosphoric acid/Kieselguhr or a zeolite and the subsequent selective hydroperoxidation of cumene to form acetone and phenol.
摘要:
A method for the production of a fluorine-containing aromatic compound is provided which allows the relevant reaction to proceed in a standard reaction vessel such as, for example, a glass vessel at room temperature under an ambient pressure without requiring provision of such special devices as have been necessary heretofore or adoption of harsh reaction conditions. This method comprises causing an aromatic compound (A) having a cyclic skeletal part of 6 to 16 carbon atoms containing a plurality of --C(.dbd.O)X groups, wherein X stands for a hydrogen atom, a halogen atom, or an alkyl group of 1 to 10 carbon atoms, and having the remaining hydrogen atoms unsubstituted or partly or wholly substituted with at least one species of halogen atom to react with a compound (B) represented by the formula: ##STR1## wherein R.sup.1 and R.sup.2 independently stand for an alkyl group of 1 to 6 carbon atoms or a phenyl group.

The invention relates to a process for the preparation of a compound of the formula (I) ##STR1## in which X is an optionally protected formyl group andR is a group which is itself inert to the reaction conditions of the synthesis,which comprises reacting a compound of the formula (II) ##STR2## where X is as defined above, with a substituted phenyl-halogen compound of the formula (III) ##STR3## where the substituent Hal is a halogen group and R is as defined above.
摘要:
The invention relates to new 4-bicyclically substituted dihydropyridines of the general formula (I) ##STR1## in which R.sub.1 to R.sub.5 have the meaning given in the description, processes for their preparation and their use in medicaments, in particular in agents for the treatment of cardiovascular diseases.
摘要:
We disclose a novel nitrile, i.e. 5,6,7,8-tetrahydro-3,5,5,6,7,8,8-heptamethyl-2-naphthalenecarbonitrile, a perfuming ingredient having a musky, earthy odor, and which is remarkably stable in particularly aggressive media such as for instance antiperspirant bases. This compound may present itself as a racemate or in the form of one of its optically active isomers.Said isomers can be obtained from aldehydes, namely (-)-(6S,7S) and (+)-(6R,7R)-5,6,7,8-tetrahydro-3,5,5,6,7,8,8-heptamethyl-2-naphtalenecarbaldehyde, which aldehydes are not only useful as starting products for the preparation of the corresponding nitriles, but also as perfuming ingredients.
