Titanocene pnictinidene complexes

The phospha-Wittig reagent Mes TerPPMe 3 ( Mes Ter = 2,6-{2,4,6-Me 3 -C 6 H 2 }-C 6 H 3 ) and arsa-Wittig reagent Dip TerAsPMe 3 ( Dip Ter = 2,6-{2,6-iPr 2 -C 6 H 3 }-C 6 H 3 ) have been employed to synthesize the titanocene complexes Cp 2 Ti(PMe 3 )PnAr (Pn = P, As) with terminal phosphinidene or a...

More Information
Summary:The phospha-Wittig reagent Mes TerPPMe 3 ( Mes Ter = 2,6-{2,4,6-Me 3 -C 6 H 2 }-C 6 H 3 ) and arsa-Wittig reagent Dip TerAsPMe 3 ( Dip Ter = 2,6-{2,6-iPr 2 -C 6 H 3 }-C 6 H 3 ) have been employed to synthesize the titanocene complexes Cp 2 Ti(PMe 3 )PnAr (Pn = P, As) with terminal phosphinidene or arsinidene ligands, respectively. Ab initio studies show that the description as singlet biradicaloids in their ground state is warranted. Phospha- and arsa-Wittig reagent have been employed to synthesize titanocene complexes with terminal phosphinidene or arsinidene ligands, respectively.
