7542-94-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7542-94-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,4 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7542-94:
(6*7)+(5*5)+(4*4)+(3*2)+(2*9)+(1*4)=111
111 % 10 = 1
So 7542-94-1 is a valid CAS Registry Number.

ONE STEP SYNTHESIS OF AZIRIDINES BY THE MICHAEL TYPE ADDITION OF FREE SULFIMIDES

Furukawa, Naomichi,Yoshimura, Toshiaki,Ohtsu, Masami,Akasaka, Takeshi,Oae, Shigeru

, p. 73 - 80 (2007/10/02)

The Michael type additions of diphenyl N-unsubstituted sulfimide (free sulfimide) to various electrophilic olefins were carried out.The reaction with cis- and trans-dibenzoylethylene, dimethylfumarate, dimethylmaleate, benzalacetophenone and benzalacetone gave mainly the corresponding trans-2-acylaziridines and trans-enaminoketones.However, phenyl vinyl sulfone or acrylonitrile afforded not the corresponding aziridine but diphenyl-N-2-cyano or N-2-phenylsulfonylethylsulfimide, a simple Michael adduct.When optically active (+)-(R)-o-methoxyphenylphenyl free sulfimide was treated with such an α,β-unsaturated carbonyl compound as benzalacetophenone, an optically active 2-acylaziridine, i.e., (-)-trans-2-benzoyl-3-phenylaziridine was obtained in ca 30percent optical purity and its absolute configuration was assigned as (2R,3S) upon chemical transformation to the configurationally known 2-phenyl-2-benzoylamino-1-ethanol or by comparing its CD spectrum with that of (1R,2R)-1-phenyl-2-benzoyl-cyclopropane.Meanwhile, (-)-(S)-o-methoxyphenylphenyl free sulfimide was found to react with benzalacetophenone to afford (+)-trans-2-benzoyl-3-phenylaziridine of 25percent optical purity.Effects of solvent and temperature on both the distribution of the products ratio and the optical yield were examined.
