254992-96-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 254992-96-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,9,9 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 254992-96:
(8*2)+(7*5)+(6*4)+(5*9)+(4*9)+(3*2)+(2*9)+(1*6)=186
186 % 10 = 6
So 254992-96-6 is a valid CAS Registry Number.

Regio- and diastereoselective three-component syntheses of homoallylic amines in aqueous media catalyzed by Bronsted acids

Deng, Dong-Sheng,Liu, Ping,Cai, Jiwen

, p. 1594 - 1598 (2007)

A systematic investigation into the three component allylation reaction of aldehydes, amines, and allyltributylstannanes catalyzed by Brensted acids in aqueous media was reported. The reaction was effective and able to produce homoallylic amines in modera

Organic Photoredox-Catalyzed Synthesis of δ-Fluoromethylated Alcohols and Amines via 1,5-Hydrogen-Transfer Radical Relay

Wang, Huiqiao,Zhang, Jinjin,Shi, Jianxue,Li, Fan,Zhang, Sheng,Xu, Kun

supporting information, p. 5116 - 5120 (2019/09/03)

The hydrotrifluoromethylation of benzyl-protected homoallylic alcohol and amine derivatives catalyzed by 2,4,5,6-tetra(9H-carbazol-9-yl)isophthalonitrile (4CzIPN) was developed. This reaction delivered δ-fluoromethylated free alcohols and amines with in situ deprotection of benzyl protecting group under mild irradiation conditions. 4CzIPN was found to be a competent metal-free photoredox catalyst for activating several types of fluoromethylation reagents including CF3SO2Cl, Togni's reagent, and 2-bromo-2,2-difluoroacetate via oxidative quenching and also CF3SO2Na through reductive quenching to allow direct hydrotrifluoromethylation of simple alkenes and Michael acceptors.

A silver triflate-catalyzed cascade of in situ-oxidation and allylation of arylbenzylamines

Wang, Junjiao,Yang, Shangdong

supporting information, p. 3444 - 3448 (2016/07/18)

A silver-triflate catalyzed cascade of in situ-oxidation and allylation of arylbenzylamines is reported. The 2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate is employed as a mild oxidant which is compatible with both catalyst and ligand. Racemic BINAP is also utilized to assist with the catalyst in regulating the yields of products. Various homoallylic amines are obtained in 39–99% yields.
