54459-33-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54459-33-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,4,5 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54459-33:
(7*5)+(6*4)+(5*4)+(4*5)+(3*9)+(2*3)+(1*3)=135
135 % 10 = 5
So 54459-33-5 is a valid CAS Registry Number.

Pd-catalyzed cross-electrophile Coupling/C-H alkylation reaction enabled by a mediator generatedviaC(sp3)-H activation

Jiang, Hang,Wu, Zhuo,Zhang, Yanghui

, p. 8531 - 8536 (2021/07/02)

Transition-metal-catalyzed cross-electrophile C(sp2)-(sp3) coupling and C-H alkylation reactions represent two efficient methods for the incorporation of an alkyl group into aromatic rings. Herein, we report a Pd-catalyzed cascade cross-electrophile coupling and C-H alkylation reaction of 2-iodo-alkoxylarenes with alkyl chlorides. Methoxy and benzyloxy groups, which are ubiquitous functional groups and common protecting groups, were utilized as crucial mediatorsviaprimary or secondary C(sp3)-H activation. The reaction provides an innovative and convenient access for the synthesis of alkylated phenol derivatives, which are widely found in bioactive compounds and organic functional materials.
