93321-12-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93321-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,3,2 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 93321-12:
(7*9)+(6*3)+(5*3)+(4*2)+(3*1)+(2*1)+(1*2)=111
111 % 10 = 1
So 93321-12-1 is a valid CAS Registry Number.

Microwave irradiation as a high-speed tool for activation of sluggish aryl chlorides in Grignard reactions

Gold, Henrik,Larhed, Mats,Nilsson, Peter

, p. 1596 - 1600 (2005)

Grignard reagents have been generated from reluctant aryl chlorides and bromides using controlled microwave heating to establish a safe, productive and reproducible method. In the synthesis of a novel HIV-1 protease inhibitor, microwave irradiation was both used to generate the starting arylmagnesium halide and to promote a subsequent Kumada coupling.

Highly active and reusable hydrotalcite-supported Pd(0) catalyst for Suzuki coupling reactions of aryl bromides and chlorides

Karanjit, Sangita,Kashihara, Masaya,Nakayama, Atsushi,Shrestha, Lok Kumar,Ariga, Katsuhiko,Namba, Kosuke

supporting information, p. 948 - 954 (2018/01/27)

A palladium(0) nanocluster supported on hydrotalcite has been prepared and tested for the Suzuki coupling reaction. The prepared catalyst showed very efficient catalytic activity for cross coupling of iodo- and bromoarenes under very mild reaction conditions, affording >90% yield. Under the optimized reaction conditions, chloroarenenes also showed very good reactivity. Transmission electron microscopic imaging data showed the formation of very small Pd(0)-nanoclusters (d = 2.2 ± 0.5 nm) well dispersed on the support, which enhanced the activity and stability of the catalyst for the Suzuki cross-coupling reaction. This catalytic system offers an easy method of preparation with good activity and reusability up to five cycles.

Nickel- or Iron-Catalyzed Cross-Coupling of Aryl Carbamates with Arylsilanes

Shi, Wen-Juan,Zhao, Hong-Wei,Wang, Yang,Cao, Zhi-Chao,Zhang, Li-Sheng,Yu, Da-Gang,Shi, Zhang-Jie

supporting information, p. 2410 - 2416 (2016/08/16)

Aryl carbamates were for the first time applied as electrophiles in the cross-coupling with arylsilanes via nickel or iron catalysis to construct valuable biaryl compounds. This new coupling reaction features a good group tolerance and non-sensitivity to steric hindrance on both aryl carbamates and arylsilanes. (Figure presented.).
