Abstract
The thermolysis of (2-methoxyphenyl)methyltitanocene (2) in the presen ce of various unsaturated substrates regioselectively to yield metalla cycles, presumably via the intermediacy of the titanocene-benzyne comp lex 3, is described. If the thermolysis is effected in the presence of trimethylphosphine, the titanocene-benzyne complex Cp2Ti(eta2-C6H4-2- OMe)(PMe3) (1a) can be isolated. The reactions of 1a and 3 are compare d to those of the analogous zirconium complexes.
