General Description
4-Bromo-2,6-di-tert-butylphenol is a 4-substituted-2,6-di-tert-butylphenol. It is synthesized by the bromination of 2,6-di-tert-butylphenol. The structure was confirmed by 1H NMR. Its photolysis reaction in benzene solution has been investigated. The photochemical reaction of 4-bromo-2,6-di-tert-butylphenol single crystals doped with 2,6-di-tert-butyl-p-quinone has been studied by EPR spectroscopy.
Check Digit Verification of cas no
The CAS Registry Mumber 1139-52-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1139-52:
(6*1)+(5*1)+(4*3)+(3*9)+(2*5)+(1*2)=62
62 % 10 = 2
So 1139-52-2 is a valid CAS Registry Number.

Mapping the active site in a chemzyme: Diversity in the N-substituent in the catalytic asymmetric aziridination of imines

(Chemical Equation Presented) The active site of the aziridination catalyst derived from either the VANOL or VAPOL ligand and B(OPh)3 is larger than expected and can accommodate not only significant substitution on the diarylmethyl unit of the imine but also that alkyl (but not perfluorylalkyl) substituents on the aryl groups lead to enhanced rates and enantioselection. The screen of diarylmethyl N-substituents on the imine revealed that the 3,5-di-tert-butyldianisylmethyl group (BUDAM) gave exceptionally high asymmetric inductions for imines of aryl aldehydes.
