60068-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60068-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,0,6 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 60068-19:
(7*6)+(6*0)+(5*0)+(4*6)+(3*8)+(2*1)+(1*9)=101
101 % 10 = 1
So 60068-19-1 is a valid CAS Registry Number.

Iron-Catalyzed Ring-Opening Reactions of Cyclopropanols with Alkenes and TBHP: Synthesis of 5-Oxo Peroxides

Lou, Chenhao,Wang, Xin,Lv, Leiyang,Li, Zhiping

, p. 7608 - 7612 (2021/10/02)

The ring opening of cyclopropanols is rarely used in multicomponent reactions. Herein we report the three-component reaction of cyclopropanols with alkenes and tert-butyl hydroperoxide (TBHP) catalyzed by an iron catalyst. This protocol enables the incorporation of both the β-carbonyl fragment and a peroxy unit across the C=C double bond regioselectively, thus allowing an efficient, facile access to 5-oxo peroxides. Modification of the biologically active molecules and various downstream derivatizations of the peroxides are also demonstrated.

Visible-Light-Induced Alkoxyl Radical Generation Enables Selective C(sp3)-C(sp3) Bond Cleavage and Functionalizations

Jia, Kunfang,Zhang, Fuyuan,Huang, Hanchu,Chen, Yiyun

, p. 1514 - 1517 (2016/02/20)

The alkoxyl radical is an important reactive intermediate in mechanistic studies and organic synthesis; however, its current generation from alcohol oxidation heavily relies on transition metal activation under strong oxidative conditions. Here we report the first visible-light-induced alcohol oxidation to generate alkoxyl radicals by cyclic iodine(III) reagent catalysis under mild reaction conditions. The β-fragmentation of alkoxyl radicals enables selective C(sp3)-C(sp3) bond cleavage and alkynylation/alkenylation reactions with various strained cycloalkanols, and for the first time with linear alcohols.

A facile cyclopropanol synthesis from β-halo ester with Grignard reagent-samarium(II) diiodide couple

Fukuzawa,Niimoto,Sakai

, p. 7691 - 7694 (2007/10/02)

Transformation of α,β-halo ester to the cyclopropanols by a coupled reagent of samarium(II) diiodide with Grignard reagent in tetrahydrofuran-hexamethylphosphoric triamide was very successful under mild conditions.
