Ren, Shujian,Fu, Jiahui,Cheng, Dongping,Li, Xiaonian,Xu, Xiaoliang
supporting information, (2021/02/09)
Induced by visible light, a green approach for the highly substituted trifluoromethyl olefins has been developed by using alkyl boronic acid as a carbon radical precursor and the Boc-modified trifluoromethylated Baylis-Hillman adduct (BMTBHA) as an accept

Paragraph 0285-0387, (2014/02/15)
A method for producing a fluorine-containing substituted compound, the method including: introducing an organofluorine compound and an organolithium compound into a microreactor provided with a flow path capable of mixing a plurality of liquids, to thereby obtain a reaction product; and introducing, into the microreactor, the reaction product and an electrophile exhibiting electrophilic effect on the reaction product, to thereby obtain a fluorine-containing substituted compound.

(Chemical Equation Presented) The reaction of (trifluoromethyl) dimethylphenylsilylacetylene and (η2-propene)Ti(O iPr)2 generated in situ smoothly proceeded giving the corresponding (η2-1-dimethylphenylsilyl-2-t
A facile synthesis of N-[2-(trifluoromethyl)allyl]amides and their transformation into angularly trifluoromethylated bicyclic cyclopentenones
Nadano, Ryo,Ichikawa, Junji
, p. 22 - 23 (2007/10/03)
On treatment with sec-BuLi at -105°C, 2-bromo-3,3,3-trifluoropropene undergoes rapid lithium-halogen exchange to generate thermally unstable 1-(trifluoromethyl)vinyllithium, which reacts with W-tosylimines to afford N-[2-(trifluoromethyl)allyl] amides in high yield. Propargylation of the amides, followed by the Pauson-Khand reaction, readily provides pyrrolidine ring-fused cyclopentenones with an angular trifluoromethyl group. Copyright
1-(Trifluoromethyl)vinylation via oxirane or oxetane ring-opening: A facile synthesis of 4- or 5-hydroxy-functionalized 2-trifluoromethyl-1-alkenes
Nadano, Ryo,Ichikawa, Junji
, p. 128 - 132 (2007/10/03)
Introduction of a 1-(trifluoromethyl)vinyl group has been accomplished by the reaction of thermally unstable 1-(trifluoromethyl)vinyllithium (1) with strained cyclic ethers. Treatment of 2-bromo-3,3,3-trifluoropropene with butyllithium generates 1, which in turn reacts with several oxiranes or an oxetane at -100 °C in the presence of BF3·OEt2 to afford the corresponding 2-trifluoromethyl-1-alkenes bearing a hydroxy group on the 4- or 5-position. An enantiopure oxirane undergoes ring-opening without racemization, providing an optically active homoallyllic alcohol with a 3-trifluoromethyl group. Georg Thieme Verlag Stuttgart.
Preparation of optically active 2-(trifluoromethyl)alkan-1-ols by catalytic asymmetric hydrogenation

, p. 5 - 6 (2007/10/02)
The hydrogenation of (E)-2-(trifluoromethyl)alk-2-en-1-ols catalyzed by Ru-BINAP and Rh-BINAP has been carried out with good enantiomeric excess (71percent-83percent ee).Ru-BINAP-catalyzed hydrogenation converted 2-trifluoromethylacrylic acid to the corresponding saturated acid, the esterification and reduction of which gave optically active 2-(trifluoromethyl)propan-1-ol in 80percent ee.
