7381-89-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7381-89-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,8 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7381-89:
(6*7)+(5*3)+(4*8)+(3*1)+(2*8)+(1*9)=117
117 % 10 = 7
So 7381-89-7 is a valid CAS Registry Number.

Synthesis Method of Cyclopropane or Cyclopentene Derivatives via Fe-catalyzed Cationic Radical Cycloaddition Reaction

-

Paragraph 0080-0081; 0101-0102, (2021/11/02)

In this disclosure Fe (III) complex is used as an electron oxidizing agent to oxidize an electron - rich alkene compound to form a radical cation intermediate, and then a cyclopropane compound or 3 5-membered ring compound is synthesized by inducing a cycloaddition reaction with the diazo compound.

A transition-metal-free & diazo-free styrene cyclopropanation

Herraiz, Ana G.,Suero, Marcos G.

, p. 9374 - 9379 (2019/10/22)

An operationally simple and broadly applicable novel cyclopropanation of styrenes using gem-diiodomethyl carbonyl reagents has been developed. Visible-light triggered the photoinduced generation of iodomethyl carbonyl radicals, able to cyclopropanate a wide array of styrenes with excellent chemoselectivity and functional group tolerance. To highlight the utility of our photocyclopropanation, we demonstrated the late-stage functionalization of biomolecule derivatives.

Rhodium Porphyrin Catalyzed Regioselective Transfer Hydrogenolysis of C-C σ-Bonds in Cyclopropanes with iPrOH

Chen, Chen,Feng, Shiyu,Chan, Kin Shing

supporting information, p. 2582 - 2589 (2019/07/02)

A new rhodium porphyrin catalyzed regioselective transfer hydrogenolysis of both activated and unactivated cyclopropanes employing iPrOH as the hydrogen source was discovered. The reaction mechanism for the C-C σ-bond activation of cyclopropanes was identified through an initial radical substitution with rhodium(II) metalloporphyrin radical to give a rhodium porphyrin alkyl, followed by hydrogenolysis with iPrOH to give the corresponding acyclic alkanes and regenerate rhodium(II) metalloporphyrin radical.
