A series of tetrathiafulvalenes functionalized with one or two trifluoromethyl electron-withdrawing groups (EWG) is obtained by phosphite coupling involving CF3-substituted 1,3-dithiole-2-one derivatives. The relative effects of the EWG such as CF3, CO2Me and CN on the TTF core were investigated from a combination of structural, electrochemical, spectrochemical and theoretical investigations. E...

Impacts of intramolecular non-covalent interactions TADF emitters on their electroluminescent performances were investigated using donor-acceptor compounds containing moiety 1,4-bis(trifluoromethyl)benzene.

Treatment of 2,2-bis(trifluoromethyl)-4-R-oxetanes (R = C₂H₅O, n-C₃H₇O, n-C₄H₉O) with BF₃.OEt₂ in CH₂Cl₂ solvent results in spontaneous electrophilic [4 + 4] cyclodimerization with the formation of the corresponding 2,2,6,6-tetrakis(trifluoromethyl)-4,8-dialkoxy-1,5-dioxocanes, isolated in 31-42% yield. The structures of two products (R = C₂H₅O and n-C₃H₇O) were established by single crystal X-...

A highly enantioselective and diastereoselective copper(II)-bisoxazolidine catalyzed nitroaldol reaction with aliphatic and aromatic trifluoromethyl ketones is described.

The isomers 4′-(4-(trifluoromethyl)phenyl)-4,2′:6′,4″-terpyridine (1), 4′-(3-(trifluoromethyl)phenyl)-4,2′:6′,4″-terpyridine (2), 4′-(4-(trifluoromethyl)phenyl)-3,2′:6′,3″-terpyridine (3), and 4′-(3-(trifluoromethyl)phenyl)-3,2′:6′,3″-terpyridine (4) have been prepared characterized. single crystal structures of 1 2 were determined. 1D-polymers [Cu2(hfacac)4(1)2]n·2nC6H4Cl2 (Hhfacac = 1,1,1,5,5...

Iterative cross-coupling represents a potentially general approach for the simple, efficient, and flexible construction of a wide range of functional small molecules. In this context, (1-bromovinyl)-N-methyliminodiacetic acid (MIDA) boronate is a very useful building block for small molecule synthesis. This compound can serve as a starting material for the preparation of a wide range of 1,1-dis...
