5629-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5629-57-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,2 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5629-57:
112 % 10 = 2
So 5629-57-2 is a valid CAS Registry Number.

Generation of reactive species by one-electron reduction of Fischer-type carbene complexes of group 6 metals and their use for carbon - Carbon bond formation

Fuchibe, Kohei,Iwasawa, Nobuharu

, p. 905 - 914 (2003)

Carbon - carbon bond-forming reactions mediated by one-electron reduction of Fischer-type carbene complexes of Group 6 metals were investigated. In the case of aryl- or silylcarbene complexes of tungsten, the anion radical species generated by one-electro

Cobalt(i)-catalysed CH-alkylation of terminal olefins, and beyond

Giedyk, Maciej,Goliszewska, Katarzyna,ó Proinsias, Keith,Gryko, Dorota

supporting information, p. 1389 - 1392 (2016/01/25)

Cobalester, a natural nontoxic vitamin B12 derivative, was found to catalyse unusual olefinic sp2 C-H alkylation with diazo reagents as a carbene source instead of the expected cyclopropanation.

Ring Expansion of Epoxides under Br?nsted Base Catalysis: Formal [3+2] Cycloaddition of β,γ-Epoxy Esters with Imines Providing 2,4,5-Trisubstituted 1,3-Oxazolidines

Kondoh, Azusa,Odaira, Kenta,Terada, Masahiro

, p. 11240 - 11244 (2016/07/06)

A novel ring-expansion reaction of epoxides under Br?nsted base catalysis was developed. The formal [3+2] cycloaddition reaction of β,γ-epoxy esters with imines proceeds in the presence of triazabicyclodecene (TBD) as a superior Br?nsted base catalyst to afford 2,4,5-trisubstituted 1,3-oxazolidines in a highly diastereoselective manner. This reaction involves the ring opening of the epoxides with the aid of the Br?nsted base catalyst to generate α,β-unsaturated esters having an alkoxide at the allylic position, which would formally serve as a synthetic equivalent of the 1,3-dipole, followed by a cycloaddition reaction with imines in a stepwise fashion. This methodology enables the facile synthesis of enantioenriched 1,3-oxazolidines from easily accessible enantioenriched epoxides.
