Metathesis reaction of formaldehyde acetals: An easy entry into the dynamic covalent chemistry of cyclophane formation

The acid-catalyzed transacetalation of formaldehyde acetals (formal metathesis) is a suitable reaction for the generation of well-behaved Dynamic Libraries of cyclophane formals. The composition of the equilibrated mixtures solely depends on concentration

NHC-CDI Betaine Adducts and Their Cationic Derivatives as Catalyst Precursors for Dichloromethane Valorization

Zwitterionic adducts of N-heterocyclic carbene and carbodiimide (NHC-CDI) are an emerging class of organic compounds with promising properties for applications in various fields. Herein, we report the use of the ICyCDI(p-Tol) betaine adduct (1a) and its cationic derivatives2aand3aas catalyst precursors for the dichloromethane valorization via transformation into high added value products CH2Z2(Z = OR, SR or NR2). This process implies selective chloride substitution of dichloromethane by a range of nucleophiles Na+Z-(preformed or generatedin situfrom HZ and an inorganic base) to yield formaldehyde-derived acetals, dithioacetals, or aminals with full selectivity. The reactions are conducted in a multigram-scale under very mild conditions, using dichloromethane both as a reagent and solvent, and very low catalyst loading (0.01 mol %). The CH2Z2derivatives were isolated in quantitative yields after filtration and evaporation, which facilitates recycling the dichloromethane excess. Mechanistic studies for the synthesis of methylal CH2(OMe)2rule out organocatalysis as being responsible for the CH2transfer, and a phase-transfer catalysis mechanism is proposed instead. Furthermore, we observed that1aand2areact with NaOMe to form unusual isoureate ethers, which are the actual phase-transfer catalysts, with a strong preference for sodium over other alkali metal nucleophiles.

Novel synthesis method of alkoxymethylamine compound

The invention relates to a novel synthesis method of an alkoxymethylamine compound. The novel synthesis method comprises the steps: (1) dehydrating formaldehyde HCHO and alcohol R1OH by carrying out an aldolization under the action of an acid catalyst to obtain dialkoxymethane; and (2) carrying out a hydrocarbylation reaction on dialkoxymethane obtained in step (1) and substituted amine R2-NH2 toremove alcohol to obtain an alkoxymethyl substituent amine compound N-R1 oxymethyl-N-R2 amine. The synthesis method disclosed by the invention is simple in operation and high in yield reaching 92% orabove; and compared with the prior art, the novel synthesis method has the advantages that no acid wastewater, waste salts and chloromethyl alkyl ether serving as a cancerogen are greatly generated, the environment protection cost is favorably reduced, and the industrial prospect is higher.
