Abstract
The [(mu-tartrato)(Cp(2)TiCH(3))(2)] complexes 2, derived from the rea ction between dimethyl and dibutyl tartrate, respectively, with dimeth yltitanocene, react with tris(pentafluorophenyl)borane to give the mon ocations [(mu-tartrato)(Cp(2)Ti)(Cp(2)TiCH(3))](+) and subsequently th e dications [(mu-tartrato)(Cp(2)Ti)(2)](2+). In dichloromethane soluti on in both cases internal ester coordination is observed, leading to m ixtures of five- and six-membered ring product isomers.
