Functionalization of Complexed N₂O in Bis(pentamethylcyclopentadienyl) Systems of Zirconium and Titanium.

ABSTRACT: Methyl triflate reacts with the metastable azoxymetallacyclopentene complex Cp*₂Zr(N(O)NCPhCPh), generated in situ from nitrous oxide insertion into the Zr-C bond of Cp*₂Zr(η²-PhCCPh) at -78 °C, to afford the salt [Cp*₂Zr(N(O)N(Me)CPhCPh)][O₃SCF₃] (1) in 48% isolated yield. A single-crystal X-ray structure of 1 features a planar azoxymetallacycle with methyl alkylation taking place only at the β-nitrogen position of the former Zr(N(O)NCPhCPh) scaffold. In addition to 1, the methoxy-triflato complex Cp*₂Zr(OMe)(O₃SCF₃) (2) was also isolated from the reaction mixture in 26% yield and fully characterized, including its independent synthesis from the alkylation
