Uses

Tribenzylamine (TBA) is a tertiary amine which can be used :As a nitrogen group source for the reactions involving C?N bond formation.For the synthesis of imine i.e. N?benzylidene benzylamine by aerobic oxidative condensation.As an extractant for the separation and determination of Cr(VI) and Cr(III) from wastewater.TBA can also undergo debenzylation in the presence of ceric ammonium nitrate (CAN) to form dibenzylamine.

Purification Methods

Crystallise the amine from absolute EtOH or pet ether. Dry it in a vacuum over P2O5 at room temperature. The hydrochloride has m 226-228o (from EtOH) and the picrate has m 191o (from H2O or aqueous EtOH). [Beilstein 12 IV 2183.]

Check Digit Verification of cas no

The CAS Registry Mumber 620-40-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 620-40:
(5*6)+(4*2)+(3*0)+(2*4)+(1*0)=46
46 % 10 = 6
So 620-40-6 is a valid CAS Registry Number.

Helical structures of tribenzylamine supramolecular complexes with [CoCl4]2-/[CuCl4]2-, and conformational comparisons of tribenzylamine in different supramolecular complexes

Guan, Hong-Yu,Shao, Hui-De,Li, Lei,Jia, Jian-Ming,Guo, Fang

, p. 471 - 477 (2013)

The compound tribenzylamine (TBA) and its derivatives are a type of classical tripodal ligands in building up diversity of supramolecular arrays or networks. In the present contribution, we described two new supramolecular complexes 2[C21H22N+]·[CoCl 4]2-·(1) and 2[C21H22N +]·[CuCl4]2- (2) by reacting protonated TBA with CoCl2·6H2O/CuCl2·2H 2O. Different from previous TBA supramolecular complexes, these two supramolecular complexes were easier to obtain by grinding protonated TBA and CoCl2·6H2O/CuCl2·2H2O in an agate mortar than using conventional solution method. The two supramolecular complexes form fascinating 3D helical architectures, with two types of interwoven helical chains involved inside the structures. A comparison of the geometries of TBA in these two supramolecular complexes with the previously reported TBA supramolecular complexes shows that the significant differences are due to the conformation of the three arms of phenyl rings around the N center.

Layered structures constructed by second-sphere coordination via N-H···Cl and C-H···Cl hydrogen bonding: Synthesis and crystal structures of tribenzylamine and [MCl6] (M=Sn, Re, and Te)

Guo, Fang,Lu, Na,Tong, Jian,Luan, Yu-Bo,Guo, Wen-Sheng

, p. 809 - 818 (2010)

A series of second-sphere coordination complexes of tribenzylamine (L1) and [MCI6] (M=Sn, Re, Te) have been synthesized and characterized by spectroscopic techniques (IR, NMR) and single-crystal X-ray diffraction. The main driving force for the encapsulation of [MCl6] and recognition with L1 is the second-sphere coordination of metal halides by the amide protons of the ligand via hydrogen bonding (N-H···Cl-M and C-H···Cl-M); new layered structures are described. Thermal stability and irreversible behavior of second-sphere coordination complexes [L2] 0.5[TeCl6]2- · HCl · (H3O)+ · 0.5H2O (L2=N,N,N′,N′-tetrabenzyl-ethylenediamine) in contact with water vapor are also described.

Reduction of Amides to Amines with Pinacolborane Catalyzed by Heterogeneous Lanthanum Catalyst La(CH2C6H4NMe2- o)3@SBA-15

Guo, Chenjun,Zhang, Fangcao,Yu, Chong,Luo, Yunjie

supporting information, p. 13122 - 13135 (2021/08/31)

Hydroboration of amides is a useful synthetic strategy to access the corresponding amines. In this contribution, it was found that the supported lanthanum benzyl material La(CH2C6H4NMe2-o)3@SBA-15 was highly active for the hydroboration of primary, secondary, and tertiary amides to amines with pinacolborane. These reactions selectively produced target amines and showed good tolerance for functional groups such as -NO2, -halogen, and -CN, as well as heteroatoms such as S and O. This reduction procedure exhibited the recyclable and reusable property of heterogeneous catalysts and was applicable to gram-scale synthesis. The reaction mechanisms were proposed based on some control experiments and the previous literature. This is the first example of hydroborative reduction of amides to amines mediated by heterogeneous catalysts.

Rapid Multialkylation of Aqueous Ammonia with Alcohols by Heterogeneous Iridium Catalyst under Simple Conditions

Yu, Han,Ma, Lin,Wada, Kenji,Kurihara, Ryohsuke,Feng, Qi,Uemura, Shinobu,Isoda, Kyosuke

, p. 3588 - 3593 (2021/07/02)

This paper reports the synthesis of tertiary and secondary amines from aqueous ammonia and benzylic alcohols by titania-supported iridium catalyst. It is a successful example of heterogeneous systems at moderate temperature without either additional solvent or high pressure. The catalytic system showed good tolerance to the atmosphere condition and performed rapidly to give tribenzylamine a yield of over 99 % within 6 hours in argon. The crystal structure of titania supports for iridium catalysts strongly affected their activity. The catalysis smoothly proceeded on larger scales. The catalyst could be easily reused and run at least for 5 cycles without significant loss of activity. The highly-dispersed iridium species of less than 2 nm in diameter would be responsible for the excellent catalytic activity. This catalyst is well applicable in multialkylation of aqueous ammonia with various primary and secondary benzylic alcohols.
