186465-05-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 186465-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,4,6 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 186465-05:
(8*1)+(7*8)+(6*6)+(5*4)+(4*6)+(3*5)+(2*0)+(1*5)=164
164 % 10 = 4
So 186465-05-4 is a valid CAS Registry Number.

Catalytic and highly enantioselective aziridination of styrene derivatives

Nishikori, Hisashi,Katsuki, Tsutomu

, p. 9245 - 9248 (1996)

Highly enantioselective catalytic aziridination of styrene derivatives was realized by using the newly designed (salen)manganese(III) complex as a catalyst.

Phosphine ligand containing benzofuran structure and preparation method and application thereof

-

Paragraph 00142-0144; 0153, (2017/08/31)

The invention discloses phosphine ligand containing a benzofuran structure and a preparation method and application thereof. The phosphine ligand is a compound with a chemical structural formula shown in a formula (I) or an enantiomer or racemate of the compound. According to the phosphine ligand disclosed by the invention, a furan nucleus is introduced, so that electron cloud density of the aromatic nucleus of the phosphine ligand is improved, and steric hindrance is changed; thus, the phosphine ligand has the characteristics of good reaction activity and high yield of 99% when being applied to palladium-catalysis Suzuki-Miyaura model reaction. The phosphine ligand containing the benzofuran structure disclosed by the invention has a simple synthesizing method, is low in cost and is suitable for palladium-catalysis Suzuki-Miyaura reaction of varieties of substances.

Anionic phospho-fries rearrangement at ferrocene: One-pot approach to P,O-substituted ferrocenes

Korb, Marcus,Schaarschmidt, Dieter,Lang, Heinrich

supporting information, p. 2099 - 2108 (2014/05/20)

For the first time the anionic phospho-Fries rearrangement has been successfully applied in ferrocene chemistry, giving access to 1,2-P,O-substituted ferrocenes. The 1,3 (O → C)-migration occurs at ferrocenyl phosphates, thiophosphates, phosphite-borane adducts, and phosphinates by treatment with a base such as lithium diisopropylamide at low temperature, whereas the highest yields were obtained starting from diethylferrocenyl phosphate. Complete reduction of the phosphonate to a primary phosphine and subsequent Stelzer P,C cross coupling allowed the synthesis of Fe(η5-C5H3-2-OMe-PPh2) (η5-C5H5) (1). The qualification of 1 as a supporting ligand in palladium-catalyzed Suzuki-Miyaura C,C couplings has been proven by the synthesis of sterically congested tri-ortho-substituted biaryls under mild reaction conditions in good to excellent yields.
