7335-36-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7335-36-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7335-36:
(6*7)+(5*3)+(4*3)+(3*5)+(2*3)+(1*6)=96
96 % 10 = 6
So 7335-36-6 is a valid CAS Registry Number.

Transition-Metal-Free Synthesis of N-Aryl Hydroxamic Acids via Insertion of Arynes

Zhang, Lanlan,Geng, Yu,Jin, Zhong

, p. 3542 - 3552 (2016/05/24)

An efficient and transition-metal-free N-arylation of amides via the insertion of arynes into the N-H bonds in the N-alkoxy amides is described. A variety of the reactive functional groups including the reactive aldehyde carbonyl group, furan ring, carbon-carbon double bonds, and free N-H bond of indole are found to be compatible with this process. In particular, the protocol is applicable in the synthesis of structurally diverse N-aryl hydroxamates and hydroxamic acids derived from N-protecting amino acids and peptides. In the presence of multiple amide N-H bonds, the N-arylation reaction can proceed selectively in the N-H bonds of terminal N-OBn amides giving rise to the desired N-aryl hydroxamates.
