16618-52-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16618-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,1 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16618-52:
(7*1)+(6*6)+(5*6)+(4*1)+(3*8)+(2*5)+(1*2)=113
113 % 10 = 3
So 16618-52-3 is a valid CAS Registry Number.

Diverse catalytic reactivity of a dearomatized PN3P?-nickel hydride pincer complex towards CO2 reduction

Li, Huaifeng,Gon?alves, Théo P.,Zhao, Qianyi,Gong, Dirong,Lai, Zhiping,Wang, Zhixiang,Zheng, Junrong,Huang, Kuo-Wei

, p. 11395 - 11398 (2018)

A dearomatized PN3P?-nickel hydride complex has been prepared using an oxidative addition process. The first nickel-catalyzed hydrosilylation of CO2 to methanol has been achieved, with unprecedented turnover numbers. Selective methylation and formylation of amines with CO2 were demonstrated by such a PN3P?-nickel hydride complex, highlighting its versatile functions in CO2 reduction.

A Catalyst-Free Process for the Direct Oxidative Synthesis of Form-anilides from Arylamines and Aldehydes under Air Atmosphere

Qin, Yuancheng,Cheng, Yuanyuan,Luo, Xubiao,Li, Mingjun,Xie, Yu,Gao, Yunhua

, p. 1900 - 1904 (2015)

An efficient and catalyst-free process for the direct oxidative synthesis of formanilides from primary aromatic amines and aliphatic aldehydes has been developed under mild aerobic oxidation conditions. The isotope-labeling experiments indicated that the oxygen atom of the formanilide originated from dioxygen.

A NHC-silyliumylidene cation for catalytic N?formylation of amines using carbon dioxide

Leong, Bi-Xiang,Teo, Yeow-Chuan,Condamines, Cloe,Yang, Ming-Chung,Su, Ming-Der,So, Cheuk-Wai

, p. 14824 - 14833 (2020/12/21)

This study describes the use of a silicon(II) complex, namely, the NHC-silyliumylidene cation complex [(IMe)2SiH]I (1, IMe =:C{N(Me)C(Me)}2), to catalyze the chemoselective N-formylation of primary and secondary amines using CO2 and PhSiH3 under mild conditions to afford the corresponding formamides as a sole product (average reaction time: 4.5 h; primary amines, average yield: 95%, average TOF: 8 h?1; secondary amines, average yield: 98%, average TOF: 17 h?1). The activity of 1 and product yields outperform the currently available non-transition-metal catalysts used for this catalysis. Mechanistic studies show that the silicon(II) center in complex 1 catalyzes the C?N bond formation via a different pathway in comparison with non-transition-metal catalysts. It sequentially activates CO2, PhSiH3, and amines, which proceeds via a dihydrogen elimination mechanism, to form formamides, siloxanes, and dihydrogen gas.

An efficient method for the N-formylation of amines under catalyst- and additive-free conditions

Xu, Zhuo-Wei,Xu, Wen-Yi,Pei, Xiao-Jun,Tang, Fei,Feng, Yi-Si

supporting information, p. 1254 - 1258 (2019/04/10)

A simple catalyst- and additive-free method for the N-formylation of amines has been developed. The advantages of this protocol include a wide range of functional group tolerance, high efficiency and a lack of required extra promoters under mild conditions. This convenient strategy will provide a facile synthesis towards N-formamide natural products and pharmaceutical derivatives. A mechanism that involves difluorocarbene is proposed for this reaction.
