1121-22-8 Usage

Chemical Properties

clear colorless to light yellow liquid

Uses

Different sources of media describe the Uses of 1121-22-8 differently. You can refer to the following data:
1. (^+)-trans-1,2-Diaminocyclohexane is employed in the synthesis of macrocyclic [3+3] hexa Schiff base. It also plays an important role in the preparation of multidentate ligands, chiral auxiliaries and chiral stationary phases. Further, it is used to prepare [2+2] macrocyclization by reacting with aliphatic dialdehydes. In addition to this, it acts as a chiral ligand, which finds application in asymmetric catalysis.
2. (±)-trans-1,2-Diaminocyclohexane was used in the synthesis of macrocyclic [3+3] hexa Schiff base. It was also employed in the synthesis of multidentate ligands, chiral auxiliaries and chiral stationary phases.

General Description

(±)-trans-1,2-Diaminocyclohexane was condensed with aliphatic dialdehydes to form [3+3] or [2+2] macrocyclization products.

Purification Methods

Purify and store the diamine as for the cis-isomer above as it is a strong base and becomes yellow on storage. [Beilstein 13 IV 1.]

Check Digit Verification of cas no

The CAS Registry Mumber 1121-22-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1121-22:
(6*1)+(5*1)+(4*2)+(3*1)+(2*2)+(1*2)=28
28 % 10 = 8
So 1121-22-8 is a valid CAS Registry Number.

Method for synthesizing trans-cyclohexyldiamine

-

Paragraph 0013; 0014; 0015, (2017/08/29)

The invention discloses a method for synthesizing trans-cyclohexyldiamine. The method comprises the following steps: by using epoxy cyclohexane as the raw material, carrying out ring opening with ammonia water, adding sulfuric acid for dewatering and salification, adding free alkali, carrying out ring opening with ammonia water, and distilling to obtain the trans-cyclohexyldiamine. The method has the advantages of high repetitiveness of the synthesis route, and simple and accessible raw materials, and provides an alternative scheme for obtaining the trans-cyclohexyldiamine pure product.

A diamine-exchange reaction of dihydropyrazines

Yamaguchi, Tadatoshi,Ito, Shigeru,Iwase, Yukiko,Watanabe, Kenji,Harano, Kazunobu

, p. 1677 - 1680 (2007/10/03)

Dihydropyrazines reacted with 1,2-diamines to form tetraazadecalins as intermediates, and then the reaction proceeded forward to dissociate into alternate dihydropyrazine and diamine, or backward to dissociate into the starting materials in certain equilibrium. The product distribution is controlled by diamine-exchange equilibrium reaction. The various equilibrium reactions were analyzed by NMR spectroscopy.

Diastereo- and enantioselective synthesis of vicinal diamines via aza-Michael addition to nitroalkenes

Enders, Dieter,Wiedemann, Juergen

, p. 1443 - 1450 (2007/10/03)

The asymmetric synthesis of protected 1,2-diamines 4 by aza-analogous Michael addition of (-)-(2S,3R,4R,5S)-1-amino-3,4-dimethoxy-2,5-bis(methoxymethyl)pyrrolid ine (ADMP) to nitroalkenes 1 in good overall yields and high enantiomeric excesses (ee = 93-96%) is described. The auxiliary constitutes a novel chiral equivalent of ammonia and is removed under reductive N-N bond cleavage with Raney nickel, which also reduces the nitro group. The absolute configuration was determined by NMR-spectroscopic methods and polarimetry.
