The rhodium compounds [Rh(C≡CCF 3 )(PEt 3 ) 3 ] ( 2 ), fac ‐[RhH(C≡CCF 3 ) 2 (PEt 3 ) 3 ] ( 3 ), and fac ‐[Rh{( E )‐CH=CHCF 3 }(C≡CCF 3 ) 2 (PEt 3 ) 3 ] ( 4 ) were synthesized by reactions of the rhodium(I) complexes [Rh(H)(PEt 3 ) 3 ] ( 1 ) and [Rh(Bpin)(PEt 3 ) 3 ] ( 5 , HBpin=pinacolborane) with the alkyne 3,3,3‐trifluoropropyne. Reactivity studies of [Rh(C≡CCF 3 )(PEt 3 ) 3 ] ( 2 ) were performed with CO and 13 CO to form [Rh(C≡CCF 3 )(CO)(PEt 3 ) 3 ] ( 7 ) and subsequently trans ‐[Rh(C≡CCF 3 )(CO)(PEt 3 ) 2 ] ( 8 ) as well as the labeled derivatives. Using 1–4 as catalysts, hydroboration reactions selectively afforded borylated building blocks.
