58125-69-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58125-69-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,1,2 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58125-69:
(7*5)+(6*8)+(5*1)+(4*2)+(3*5)+(2*6)+(1*9)=132
132 % 10 = 2
So 58125-69-2 is a valid CAS Registry Number.

Copper(II)-Catalyzed Benzylic C(sp3)-H Aerobic Oxidation of (Hetero)Aryl Acetimidates: Synthesis of Aryl-α-ketoesters

Kumar, Yogesh,Jaiswal, Yogesh,Kumar, Amit

, p. 12247 - 12257 (2016/12/23)

A straightforward method is developed in this paper for the synthesis of α-ketoesters through copper-catalyzed aerobic oxidation of (hetero)aryl acetimidates using molecular oxygen as a sustainable oxidant. The reaction represents the first example of the direct synthesis of aryl-α-ketoesters from arylacetimidates through the aerobic oxidation of a benzylic C(sp3)-H (CO) bond in moderate to good yield. This transformation occurs under mild reaction conditions with a wide range of substrates and utilizes a readily available oxidant and catalyst. The synthetic utility of this transformation is demonstrated through scaled-up synthesis. A plausible reaction mechanism is also proposed.
