20828-66-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20828-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,2 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20828-66:
(7*2)+(6*0)+(5*8)+(4*2)+(3*8)+(2*6)+(1*6)=104
104 % 10 = 4
So 20828-66-4 is a valid CAS Registry Number.

Ligand-controlled cobalt-catalyzed remote hydroboration and alkene isomerization of allylic siloxanes

Huang, Jiaxin,Li, Jie,Yang, Wen,Zhang, Kezhuo,Zhao, Pei,Zhao, Wanxiang

supporting information, p. 302 - 305 (2022/01/03)

The Co-catalyzed remote hydroboration and alkene isomerization of allylic siloxanes were realized by a ligand-controlled strategy. The remote hydroboration with dcype provided borylethers, while xantphos favored the formation of silyl enol ethers.

The synthesis of N-heterocycles is of paramount importance for the pharmaceutical industry. They are often synthesized through atom economic and environmentally unfriendly methods, generating significant waste. A less explored, but greener, alternative is

Rhodium-Catalyzed Remote C(sp3)?H Borylation of Silyl Enol Ethers

Li, Jie,Qu, Shuanglin,Zhao, Wanxiang

supporting information, p. 2360 - 2364 (2020/01/02)

A rhodium-catalyzed remote C(sp3)?H borylation of silyl enol ethers (SEEs, E/Z mixtures) by alkene isomerization and hydroboration is reported. The reaction exhibits mild reaction conditions and excellent functional-group tolerance. This method is compatible with an array of SEEs, including linear and branched SEEs derived from aldehydes and ketones, and provides direct access to a broad range of structurally diverse 1,n-borylethers in excellent regioselectivities and good yields. These compounds are precursors to various valuable chemicals, such as 1,n-diols and aminoalcohols.
