14990-93-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14990-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,9 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 14990-93:
(7*1)+(6*4)+(5*9)+(4*9)+(3*0)+(2*9)+(1*3)=133
133 % 10 = 3
So 14990-93-3 is a valid CAS Registry Number.

Solid-supported Pt-catalyzed remote C-H etherification of arylamines: A simple and practical approach for the synthesis of aromatic ethers

Han, Junfen,Wang, Guodong,Sun, Jian,Li, Hongshuang,Duan, Guiyun,Li, Furong,Xia, Chengcai

, (2019)

A simple and practical approach for a direct remote C-H etherification of arylamines with alcohol is developed herein by using a solid-supported Pt catalyst, hence providing a valuable method for the synthesis of aromatic ethers. The catalyst can easily b

Copper(ii) mediatedorthoC-H alkoxylation of aromatic amines using organic peroxides: efficient synthesis of hindered ethers

Ghosh, Subhash Chandra,Sahoo, Tapan,Sarkar, Souvik,Sen, Chiranjit

supporting information, p. 8949 - 8952 (2021/09/10)

Synthesis of hindered alkyl aryl ether derivatives (R-O-Ar) remains a huge challenge and highly desirable in organic and medicinal chemistry because extensive substitution on the ether bond prevents the undesired metabolic process and thus avoids rapid de

Copper-Catalyzed Electrophilic Ortho C(sp2)-H Amination of Aryl Amines: Dramatic Reactivity of Bicyclic System

Begam, Hasina Mamataj,Choudhury, Rajarshee,Behera, Ashok,Jana, Ranjan

supporting information, p. 4651 - 4656 (2019/06/17)

A practical copper-catalyzed, 2-picolinamide-directed ortho C-H amination of anilines with benzoyl-protected hydroxylamines has been disclosed that proceeds smoothly without any external stoichiometric oxidant or additives. Remarkably, besides anilines, b
