Highly labile cationic tris-acetonitrile complexes, [TpRM(NCMe)3]OTf (M = Ni, Co; TpR: hydrotrispyrazolylborato, R = Ph, Me and iPr2): versatile precursors for TpR-containing nickel and cobalt complexes†
Abstract
The cationic tris-MeCN adducts of TpRM fragments, [TpRM(NCMe)3]OTf [TpR
= hydrotrispyrazolylborato, R = 3-Ph-5-Me (1), 3,5-iPr2
(1′); M = Ni, Co], were prepared by chloride abstraction from the corresponding chloro complexes, TpRM–Cl (2), with AgOTf in
