54043-60-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54043-60-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,0,4 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54043-60:
(7*5)+(6*4)+(5*0)+(4*4)+(3*3)+(2*6)+(1*0)=96
96 % 10 = 6
So 54043-60-6 is a valid CAS Registry Number.

Efficient monomethylation synthesis method of aromatic primary amine

-

Paragraph 0026; 0027; 0028, (2019/05/15)

The invention relates to the field of organic synthesis, in particular to an efficient monomethylation synthesis method of aromatic primary amine. The method comprises the steps as follows: aromatic primary amine is used as a material to react with formaldehyde or paraformaldehyde, and a corresponding hexahydro-1,3,5-triaryl-1,3,5-triazine compound is obtained; the compound is subjected to catalytic hydrogenation under the action of a Pd/C catalyst, and a monomethylate of aromatic primary amine is obtained. The method has the greatest characteristics that the operation is simple, the conditionis mild, the raw material is cheap and easy to obtain, and the monomethylate of aromatic primary amine with high yield and high selectivity can be obtained. Posttreatment is simple, the production efficiency is improved, industrial mass production can be realized easily, and no equipment corrosion or environmental pollution can be caused.

Synthesis of N-substituted 1,3,5-triazacyclohexanes catalyzed by starch sulfuric acid

Wu, Hui,Yuan, Rui,Wan, Yu,Yin, Wei,Pang, Li-Ling

experimental part, p. 1097 - 1102 (2012/03/11)

N-substituted 1,3,5-triazacyclohexanes were simply synthesized from the reaction of aromatic or fatty amines and formaldehyde catalyzed by recyclable starch sulfuric acid with good yields at room temperature.

Preparation of N,O-Aminals as Synthetic Equivalents of H2C=NAr and (H2C=NHAr)+ ions: Neutral- and Acid-promoted Transformations

Barluenga, Jose,Bayon, Ana M.,Campos, Pedro,Asensio, Gregorio,Gonzalez-Nunez, Elena,Molina, Yolanda

, p. 1631 - 1636 (2007/10/02)

A general method for the synthesis of N, O-aminals derived from primary aromatic amines is described.The reactivity of these compounds under neutral and acidic conditions has been studied and the title compounds can be envisaged as general purpose H2C=NAr or (H2C=NAr)+ equivalents.N,O-Aminals have been converted into perhydrotriazines by moderate heating and into bis(4-aminoaryl)methane derivatives or N-benzylarylamines, respectively, when heated in acidid media with pH control.Reduction od N,O-acetals with sodium cyanoborohydride has revealed that the C-O bond is broken exclusively in acidic media.
