Hree-component reaction of benzylamines, diethyl phosphite and triethyl orthoformate: Dependence of the reaction course on the structural features of the substrates and reaction conditions

The reaction between benzyl amines, triethyl orthoformate, and diethyl phosphite affords either bisphosphonic (compound 1) or N-benzylaminobenzylphosphonic (compound 2) acid depending on the reaction conditions. The final output of the reaction can be manipulated by the choice of reaction conditions, particularly the molar ratio of substrates.

Method For Preparing Formamidines

A method for preparing formamidines of formula (I) in a single step by reducing ureas of formula (II) using silanes of formula (III), according to reaction (II)+(III)+(I) is provided. The present invention also provides a method for preparing insecticides

Selective N-methylation of aliphatic amines with CO2 and hydrosilanes using nickel-phosphine catalysts

A method using CO2 and PhSiH3 for the methylation of primary and secondary aliphatic amines catalyzed by Ni (0) complexes was developed, selectively producing the monomethylated products in moderate to good yields. For that purpose, two catalysts were used: [(dippe)Ni(μ-H)]2 and the commercially available Ni(COD)2/dcype, both of which were rather efficient in this process. With a slight experimental modification, the reaction allowed the production of monomethylated ureas in good yields by using low amounts of PhSiH3. On the basis of the experimental results, we propose a possible reaction mechanism for the formation of the new C-N bond.

Investigation of the reaction of 3,5-diamidino-4-nitropyrazole with amines

The interaction of 3,5-bis(N,N-dimethylaminomethylene)amino-1-methyl-4-nitropyrazole with amines proceeds regioselectively with the formation of 3-amino-5-(N,N-dimethylaminomethylene)amino-1- methyl-4-nitropyrazole. Amines are converted in this way into N

A Convenient Synthesis of N-Substituted Formamidines by Desulfurization of the Corresponding Thioureas

N,N'-Di- and N,N,N'-trisubstituted thioureas were easily desulfurized by Raney nickel to yield the corresponding formamidines, while N-monosubstituted thioureas gave N,N'-disubstituted formamidines.

AMIDINES. PART VI. CORRELATION OF BASICITY OF N,N'-DISUBSTITUTED AMIDINES WITH BASICITY OF CORRESPONDING AMINES

The series of N,N'-dialkylformamidines has been synthesized and their pKa values in 98.5percent ethanol determined.It was found that there was a good, common for both N,N'-dialkyl- as well as for N,N'-diarylformamidines, correlation between the
