Abstract

We have synthesized a new nickel enolate [(PhCOCF2) Ni (dcpe)][FB (C6F5) 3] featuring fluorine atoms on the enolate moiety via B (C6F5) 3-promoted C–F bond activation of α, α, α- trifluoroacetophenone. X-ray diffraction study of [(PhCOCF2) Ni (dcpe)][FB (C6F5) 3] revealed that the complex had adopted an η3-oxallyl coordination mode in the crystal lattice. The reaction of t BuNC with [(PhCOCF2) Ni (dcpe)][FB (C6F5) 3] resulted in the ...
