Synthesis of N,N′-bis(alkyloxymethyl)piperazines and examination of their antimicrobial properties
Three-component condensation of piperazine with formaldehyde and aliphatic alcohols was employed for elucidating the possibility to synthesize N,N′-bis(alkyloxymethyl)piperazines. The structure of the resulting compounds was identified by 1H NMR spectrosc
Method for preparing N-methoxymethylamine compound
The invention provides a method for preparing an N-methoxymethylamine compound. The method comprises that oxygen or air as an oxygen source and methanol as a solvent undergoes a selective oxidation reaction to produce formaldehyde under catalysis action and the formaldehyde and amine undergo a nucleophilic reaction so that methanol condensation is further finished and the N-methoxymethylamine compound is obtained. The method has a high raw material use ratio. The used catalyst is cheap and easily obtainable, is easy to recover, can be recycled and can be easily separated from a product. The product has excellent performances, is easy to separate and purify and has high purity. The method has the great significance for alleviating the excess production capacity of methanol and developing downstream products of methanol.

Synthesis of bis- and tris-organophosphorus substituted amines and amino acids with PCH2N Fragments
The aminomethylation of the derivatives of trivalent organophosphorus acids, containing PH and POSiMe3 fragments with various bis- and tris(alkoxymethyl)amines and bis(alkoxymethyl)amino acids, is proposed as a convenient method for the synthesis of new bis- and trisphosphorylated amines and amino acids as well as their derivatives with four and five coordinated phosphorus. Also the three-components systems of phosphorous acid, paraformaldehyde, and amines are thoroughly investigated via the treatment of reaction mixtures with bis(trimethylsilyl)amine.
