191084-78-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 191084-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,0,8 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 191084-78:
(8*1)+(7*9)+(6*1)+(5*0)+(4*8)+(3*4)+(2*7)+(1*8)=143
143 % 10 = 3
So 191084-78-3 is a valid CAS Registry Number.

Novel and effective synthesis of trifluoromethylated amines by use of an Et3GeNa/C6H5SCF3 combination

Yokoyama, Yasuo,Mochida, Kunio

, p. 3443 - 3446 (1997)

Efficient synthesis of trifluoromethylated amine derivatives by use of an Et3GeNa/C6H5SCF3 combination is described. This reaction proceeded smoothly to give the desired compound in excellent yield.

Palladium(II)-Catalyzed Enantioselective Synthesis of α-(Trifluoromethyl)arylmethylamines

Johnson, Thomas,Luo, Bo,Lautens, Mark

, p. 4923 - 4930 (2016/07/06)

We describe a method for the synthesis of α-(trifluoromethyl)arylmethylamines that consists of the palladium(II)-catalyzed addition of arylboroxines to imines derived from trifluoroacetaldehyde. Palladium acetate is used as a catalyst with electron-neutral or electron-rich arylboroxines, and it was found that addition of an ammonium or silver salt was crucial to promote the reaction of electron-poor boroxines. With (S)-t-Bu-PyOX as the chiral ligand, this method delivers a variety of α-trifluoromethylated amines in 57-91% yield and with greater than 92% ee in most cases.

Enantioselective Pd-catalyzed hydrogenation of fluorinated imines: Facile access to chiral fluorinated amines

Chen, Mu-Wang,Duan, Ying,Chen, Qing-An,Wang, Duo-Sheng,Yu, Chang-Bin,Zhou, Yong-Gui

supporting information; body text, p. 5075 - 5077 (2011/02/19)

An enantioselective hydrogenation of simple fluorinated imines has been developed using Pd(OCOCF3)2/(R)-Cl-MeO-BIPHEP as a catalyst, and up to 94% ee was achieved. This method provides an efficient route to enantioenriched fluorinated amines.
