Zwitterionic and Cationic Titanium and Vanadium Complexes Having Terminal M−C Multiple Bonds. The Role of the β-Diketiminate Ligand in Formation of Charge-Separated Species
Autor: Falguni Basuli, John C. Huffman, Debashis Adhikari, Justin H. Orlando, Maren Pink, Xinfeng Gao, Daniel J. Mindiola
Publikováno v: Organometallics. 28:4115-4125
Treatment of the neopentylidene complex ([ArNC(Me)]2CH)Ti═CHtBu(OTf) (1) with a strong base such as an alkyl reagent (lithium or potassium salt) results in deprotonation of the β-diketiminate β-methyl group to form complex (ArN(Me)CCHC(CH2)NAr)Ti
