Pyrrolidine, 1,1'-(1-methyl-1,2-ethanediyl)bis-, also known as N,N'-dimethylethylenediamine or DMEDA, is an organic compound with the chemical formula C6H14N2. It is a colorless, viscous liquid that is soluble in water and most organic solvents. DMEDA is a versatile reagent in organic synthesis, particularly in the formation of cyclic compounds and as a ligand in coordination chemistry. It is also used as a catalyst in various chemical reactions, such as the synthesis of polyurethane foams and epoxy resins. Due to its potential health risks, including irritation to the eyes, skin, and respiratory system, as well as its classification as a hazardous substance, it is important to handle DMEDA with proper safety precautions.

1822-46-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1822-46-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1822-46:
(6*1)+(5*8)+(4*2)+(3*2)+(2*4)+(1*6)=74
74 % 10 = 4
So 1822-46-4 is a valid CAS Registry Number.

N-Alkylation d'amines en catalyse homogene. Synthese de mono- et de diamines cycliques

Bitsi, G.,Schleiffer, E.,Antoni, F.,Jenner, G.

, p. 343 - 352 (2007/10/02)

Ruthenium compounds are appropriate catalysts in the N-alkylation of amines.The synthesis of N-alkylated cyclic amines from a cyclic amine and an alcohol or via the condensation between a diol and a primary amine are described.The reaction with cyclic amines is highly selective, especially in the presence of a phosphine, making it a high yielding preparative procedure.The catalytic condensation between cyclic amines and diols yields either an aminoalcohol (A) or a bicyclic diamine (B).The temperature, the presence of phosphine, and the ratio of amine to diol are decisive in directing the reaction toward A or B.The proposed mechanism involves the dehydrogenation of the alcohol followed by attack of the amine on the aldehyde intermediate.

Polyfunctionalized N-Tensides. VII. Substitution and Elimination in the Reaction of 1,2-Dihalogenoalkanes with Amines

Beger, J.,Meerbote, E.

, p. 12 - 22 (2007/10/02)

1,2-Dichloroalkanes, 1,2-Dibromoalkanes and mixtures of 1-bromo-2-chloroalkanes and 1-chloro-2-bromoalkanes react with primary or secondary amines and give both elimination and substitution products, often in a nearly 1:1 proportion.The elimination products are the cis and trans-1-halo-1-alkenes, the 2-halo-1-alkenes, the 1,3- and 2,4-dienes and the 1-alkenes.The main substitution products are the 1,2-bis-aminoalkanes.Physical dates, 1H-n.m.r.-spectra,surface tension values and CMC-dates are given.
