32565-42-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 32565-42-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,5,6 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 32565-42:
(7*3)+(6*2)+(5*5)+(4*6)+(3*5)+(2*4)+(1*2)=107
107 % 10 = 7
So 32565-42-7 is a valid CAS Registry Number.

Enantioselective CO2 Fixation Via a Heck-Coupling/Carboxylation Cascade Catalyzed by Nickel

Cerveri, Alessandro,Giovanelli, Riccardo,Sella, Davide,Pedrazzani, Riccardo,Monari, Magda,Nieto Faza, Olalla,López, Carlos Silva,Bandini, Marco

, p. 7657 - 7662 (2021)

A novel asymmetric nickel-based procedure has been developed in which CO2 fixation is achieved as a second step of a truncated Heck coupling. For this, a new chiral ligand has been prepared and shown to achieve enantiomeric excesses up to 99 %. The overall process efficiently furnishes chiral 2,3-dihydrobenzofuran-3-ylacetic acids, an important class of bioactive products, from easy to prepare starting materials. A combined experimental and computational effort revealed the key steps of the catalytic cycle and suggested the unexpected participation of Ni(I) species in the coupling event.

OXIDATIVE COUPLING REACTION OF 2-HALOPHENOLS WITH K3Fe(CN)6 IN BENZENE SOLUTION

Tashiro, Masashi,Yoshiya, Haruo

, p. 653 - 660 (2007/10/02)

The oxidative coupling of twelve 2-halophenols (1a-1l) was carried out with K3Fe(CN)6 in benzene solution to obtain the corresponding dibenzofuran derivatives.However, only a small amount of the desired dibenzofurans such as 2,6-di-tert-butyl-8-methoxybenzofuran-1,4-quinone (9) and 4,8-di-tert-butyl-2,6-di-isopropyl-1-hydroxydibenzofuran (11) were obtained from 2-bromo-6-tert-butyl-4-methoxy- (1d) and 2-bromo-4-tert-butyl-6-isopropylphenol (1g), respectively.In the other cases, alternative type of products or tarry materials were formed.
