53847-33-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53847-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,8,4 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53847-33:
(7*5)+(6*3)+(5*8)+(4*4)+(3*7)+(2*3)+(1*3)=139
139 % 10 = 9
So 53847-33-9 is a valid CAS Registry Number.

Copper-Catalysed Electrophilic Amination of Aryl(alkenyl) Boronic Acids with Nitrogen-Containing Hypervalent Iodine (III) Reagent

Hu, Yuanyuan,Zheng, Songlin,Fan, Wu,Yuan, Weiming

supporting information, p. 4701 - 4707 (2021/08/23)

A copper-catalysed electrophilic N-imination of aryl(alkenyl) boronic acids with a stable hypervalent iodine(III) reagent containing a transferable (diarylmethylene)amino group is developed. The electrophilic C?N cross-coupling reaction proceeds smoothly at room temperature under oxidant-free and base-free conditions, which is further characterized by the broad functional group compatibility, thereof, extending the N-electrophile scope of electrophilic C?N cross-coupling outside the limitation of N?O and N?Cl reagents. (Figure presented.).

PROCESS FOR THE PREPARATION OF AMINOARYL- AND AMINOHETEROARYL BORONIC ACIDS AND ESTERS

-

Page/Page column 14; 15; 16; 17, (2014/12/09)

The present invention relates to a process for the preparation of aminoaryl- and aminoheteroaryl boronic acids and esters thereof of formula (I) in high yield. The claimed process uses diarylketal formula (V) to generate an arylbromide of formula (III) in which the amino-group is protected as bisarylmethylidenimino-group, which is then transformed into a formula (I) compound.
