A domino hydroboration/trifluoromethylation (formal hydrotrifluoromethylation) of alkynes using the fluoroform-derived [CuCF3] reagent is achieved. Synthetically useful (E)-alkenyl-CF3 building blocks and 1,1-bis(trifluoromethyl)-substituted alkenes can be prepared under ambient conditions in one pot/one step from alkynes. The ultimate source of CF3 is the inexpensive industrial waste fluoroform.
Synthesis of 2-Aryl-3-trifluoromethylquinolines Using (<i>E</i>)-Trimethyl(3,3,3-trifluoroprop-1-enyl)silane
The Hiyama cross-coupling reaction of (E)-trimethyl (3,3,3-trifluoroprop-1-enyl)silane (1) with 2-iodoaniline (2) proceeded without any protection of the amino group. The coordination of copper(II) fluoride to 2,2'-bipyridyl provided the fluoride source required to trigger this reaction, affording (E)-2-(3,3,3-trifluoroprop-1-enyl)aniline (3). In the presence of a stoichiometric amount of [Cu(OTf)](2)center dot C6H6, the treatment of 3 with an aryl aldehyde at 200 degrees C provided the 2-aryl-3-trifluoromethylquinoline (4) via the oxidative cyclization of an in situ-generated imine substructure.

A domino approach of Heck coupling was used to synthesize beta-trifluoromethylstyrene derivatives from iodoarenes and 1-iodo-3,3,3-trifluoropropane in moderate to good yields. This method avoids the use of low-boiling, gaseous reagents such as 3,3,3-trifluoropropene, and additives and phosphines in the catalytic system.
