84269-42-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84269-42-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,6 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84269-42:
(7*8)+(6*4)+(5*2)+(4*6)+(3*9)+(2*4)+(1*2)=151
151 % 10 = 1
So 84269-42-1 is a valid CAS Registry Number.

Asymmetric Epoxidation of Enones Promoted by Dinuclear Magnesium Catalyst

Jaszczewska-Adamczak, Joanna A.,Mlynarski, Jacek

supporting information, p. 4247 - 4255 (2021/07/17)

Asymmetric synthesis with cheaper and non-toxic alkaline earth metal catalysts is becoming an important and sustainable alternative to conventional catalytic methodologies mostly relying on precious metals. In spite of some sustainable methods for enantioselective epoxidation of enones, the development of a well-defined and efficient catalyst based on magnesium complexes for these reactions is still a challenging task. In this perspective, we present the application of chiral dinuclear magnesium complexes for asymmetric epoxidation of a broad range of electron-deficient enones. We demonstrate that the in situ generated magnesium-ProPhenol complex affords enantioenriched oxiranes in high yields and with excellent enantioselectivities (up to 99% ee). Our extensive study verifies the literature data in this area and provides a step forward to better understand the factors controlling the oxygenation process. Elaborated catalyst offers mild reaction conditions and a truly wide substrate scope. (Figure presented.).

Epoxidation of 2-Butene-1,4-diones with Hydrogen Peroxide in the Presence of a Catalytic Amount of Quaternary Ammonium Iodide

Sayama, Shinsei,Inamura, Yutaka

, p. 1993 - 1995 (2007/10/02)

The epoxidation of 1,4-disubstituted 2-butene-1,4-diones with 30percent aq.H2O2 in the presence of a catalytic amount of quaternary ammonium iodide afforded 2,3-epoxy-1,4-butanediones in high yield.
