The phospha-Wittig reagent MesTerPPMe3 (MesTer = 2,6-{2,4,6-Me3-C6H2}-C6H3) and arsa-Wittig reagent DipTerAsPMe3 (DipTer = 2,6-{2,6-iPr2-C6H3}-C6H3) have been employed to synthesize the titanocene complexes Cp2Ti(PMe3)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.
磷叶立德试剂MesTerPPMe3（MesTer = 2,6-{2,4,6-Me3-C6H2}-C6H3）和砷叶立德试剂DipTerAsPMe3（DipTer = 2,6-{2,6-iPr2-C6H3}-C6H3）已被用于分别合成带有末端膦亚基或胂亚基配体的二茂钛配合物Cp2Ti(PMe3)PnAr（Pn = P，As）。从头算研究表明，将它们的基态描述为单线态双自由基是合理的。
