Uses
Used in Chemical Synthesis:
Copper(I) trifluoromethanesulfonate benzene complex is used as a catalyst for the synthesis of enol-esters via copper(I) carboxylate intermediate formation. This process is crucial in the preparation of various organic compounds and pharmaceuticals.
Used in Enantioselective Allylic Oxidation:
In the enantioselective allylic oxidation of cyclic alkenes, copper(I) trifluoromethanesulfonate benzene complex serves as a catalyst to selectively produce enantiomerically pure products. This selective oxidation is essential in the synthesis of chiral compounds and pharmaceuticals.
Used in the Preparation of 2,5-Disubstituted Pyrrolidine Derivatives:
Copper(I) trifluoromethanesulfonate benzene complex is used as a catalyst to prepare 2,5-disubstituted pyrrolidine derivatives from N-alkenyl, alkynyl, and alkyl N-benzoyloxysulfonamides via the sulfonamidyl radical formation. These pyrrolidine derivatives are important building blocks in organic chemistry and pharmaceuticals.
Used in Asymmetric Conjugate Additions:
In combination with amino acid-based chiral phosphine ligands, copper(I) trifluoromethanesulfonate benzene complex is used to catalyze asymmetric conjugate additions of alkylzincs to acyclic α,β-unsaturated ketones. This reaction affords β-alkylcarbonyls in high yield and with excellent enantioselectivity, which are valuable intermediates in the synthesis of biologically active compounds and pharmaceuticals.
Check Digit Verification of cas no
The CAS Registry Mumber 42152-46-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,1,5 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 42152-46:
(7*4)+(6*2)+(5*1)+(4*5)+(3*2)+(2*4)+(1*6)=85
85 % 10 = 5
So 42152-46-5 is a valid CAS Registry Number.
