219753-93-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 219753-93-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,5 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 219753-93:
(8*2)+(7*1)+(6*9)+(5*7)+(4*5)+(3*3)+(2*9)+(1*3)=162
162 % 10 = 2
So 219753-93-2 is a valid CAS Registry Number.

Amination of Arylboronic Compounds via the Copper-Catalyzed Addition of Arylboronic Esters to Azodicarboxylates

Uemura, Takeshi,Yamaguchi, Mao,Chatani, Naoto

, p. 3746 - 3750 (2015)

Arylboronic esters add to di-tert-butyl azodicarboxylate under mild reaction conditions (at room temperature) to afford aryl-substituted hydrazine derivatives in good yields. The reaction tolerates a wide variety of functional groups.

Cp?Rh(III)-catalyzed electrophilic amination of arylboronic acids with azo compounds for synthesis of arylhydrazides

Lau, Yan-Fung,Chan, Chun-Ming,Zhou, Zhongyuan,Yu, Wing-Yiu

supporting information, p. 6821 - 6825 (2016/07/21)

A [Cp?Rh(iii)]-catalyzed electrophilic amination of arylboronic acids with diethyl azodicarboxylate (DEAD) was developed, and arylhydrazides were produced in excellent yields and selectivity. The analogous amination with the arylazocarboxylates afforded t

Copper salt catalyzed addition of arylboronic acids to azodicarboxylates

Uemura, Takeshi,Chatani, Naoto

, p. 8631 - 8634 (2007/10/03)

The addition of arylboronic acids 1 to azodicarboxylates 2 in the presence of a catalytic amount of a copper salt under mild reaction conditions gives aryl-substituted hydrazines 3 in high yields. The reaction is tolerant of a wide variety of functional groups.
