Preparation method 1,3 - diacyl benzene

The preparation method of 1-3 - diacyl benzene comprises the following steps: reacting m-phthalic aldehyde with an alkyl magnesium halide to form an intermediate as shown II. The intermediate shown in Formula II is subjected to an oxidation reaction under the action of an oxidant to generate III, 1 diacyl benzene as shown 3 . In-flight R1 . R2 Alkyl groups from the alkyl magnesium halides, respectively. The method has the advantages of simple process, safety, environmental protection, high target product yield, high purity and the like, and can realize large-scale industrial production.

One-pot synthesis of chiral alcohols from alkynes by CF3SO3H/ruthenium tandem catalysis

A practical one-pot synthesis of chiral alcohols from readily available alkynes via tandem catalysis by the combination of CF3SO3H and a fluorinated chiral diamine Ru(ii) complex in aqueous CF3CH2OH is described. Very interestingly, the combination of fluorinated catalysts and solvent exhibits a positive fluorine effect on the reactivity and enantioselectivity. A range of chiral alcohols with wide functional group tolerance was obtained in high yield and excellent stereoselectivity under simple and mild conditions.

Advantageous asymmetric ketone reduction with a competitive hydrogenation/transfer hydrogenation system using chiral bifunctional iridium catalysts

Hydrogenation of aromatic ketones with chiral bifunctional amidoiridium complexes proceeds in preference to transfer hydrogenation in methanol, in which the pressurised hydrogen can suppress unintended racemisation of the alcoholic product, leading to enh
