1613-89-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1613-89-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1613-89:
(6*1)+(5*6)+(4*1)+(3*3)+(2*8)+(1*9)=74
74 % 10 = 4
So 1613-89-4 is a valid CAS Registry Number.

A Highly Selective Manganese-Catalyzed Synthesis of Imines under Phosphine-Free Conditions

Chai, Huining,Yu, Kun,Liu, Bo,Tan, Weiqiang,Zhang, Guangyao

, p. 217 - 226 (2020/01/31)

An efficient and highly selective phosphine-free NN-manganese(I) complex catalyst system was developed for the acceptorless dehydrogenative coupling of alcohols with amines to form imines. The coupling reactions underwent at 3 mol % catalyst loading, and a large range of alcohols and amines with diverse functional groups was applied, including challenging diol and diamine. The target imine products were obtained in good to excellent yields. The present work provides an alternative method to construct highly active nonprecious metal complex catalysts based on phosphine-free ligands.

Rhodium-catalyzed synthesis of imines and esters from benzyl alcohols and nitroarenes: Change in catalyst reactivity depending on the presence or absence of the phosphine ligand

Song, Taemoon,Park, Ji Eun,Chung, Young Keun

, p. 4197 - 4203 (2018/04/14)

The [Rh(COD)Cl]2/xantphos/Cs2CO3 system efficiently catalyzes the reductive N-alkylation of aryl nitro compounds with alcohols by a borrowing-hydrogen strategy to afford the corresponding imine products in good to excellent yields. In the absence of xantphos, the [Rh(COD)Cl]2/Cs2CO3 catalytic system behaves as an effective catalyst for the dehydrogenative coupling of alcohols to esters, with nitrobenzene as a hydrogen acceptor. The reactivity of the rhodium catalytic system can be easily manipulated to selectively afford the imine or ester.

Synergistic Photoredox Catalysis and Organocatalysis for Inverse Hydroboration of Imines

Zhou, Nengneng,Yuan, Xiang-Ai,Zhao, Yue,Xie, Jin,Zhu, Chengjian

supporting information, p. 3990 - 3994 (2018/03/21)

The first catalytic inverse hydroboration of imines with N-heterocyclic carbene (NHC) boranes has been realized by means of cooperative organocatalysis and photocatalysis. This catalytic combination provides a promising platform for promoting NHC-boryl radical chemistry under sustainable and radical-initiator-free conditions. The highly important functional-group compatibility and possible application in late-stage hydroborations represent an important step forward to an enhanced α-amino organoboron library.
