Reactions of transition-metal oxo complexes with B(C6F5)3: crystal structures of [V{OB(C6F5)3} (acac)2], [Ti{OB(C6F5)3} (acac)2] and cis-[MoO{OB(C6F5 )3}(acac)2] (acac = acetylacetonate)

Abstract

The transition-metal oxo complexes [VO(acac) 2 ], [{TiO(acac) 2 } 2 ] and cis-[MoO 2 (acac) 2 ] (acac = C 5 H 7 O 2 ) reacted with the strong Lewis acid B(C 6 F 5 ) 3 to give the structurally characterized complexes [V{OB(C 6 F 5 ) 3 }(acac) 2 ], [Ti{OB(C 6 F 5 ) 3 }(acac) 2 ] and cis-[MoO{OB(C 6 F 5 ) 3 } (acac) 2 ]. The MO–B moiety is essentially linear.
