A radical coupled pathway to a stable and terminally bound titanium methylidene

A radical coupled pathway to a stable and terminally bound titanium methylidene

Radical coupling or oxidation of the titanium(iii)dimethyl precursor (PNP)Ti(CH ) produced the dimethyl compounds, (PNP)Ti(CH ) (X) (X = TEMPO, OMes*, OTf), which then thermally extrude methane to cyclometallate (X = TEMPO) or form the methylidene (X = OMes* or OTf). Various NMR spectral experiments...

Zusammenfassung:Radical coupling or oxidation of the titanium(iii)dimethyl precursor (PNP)Ti(CH ) produced the dimethyl compounds, (PNP)Ti(CH ) (X) (X = TEMPO, OMes*, OTf), which then thermally extrude methane to cyclometallate (X = TEMPO) or form the methylidene (X = OMes* or OTf). Various NMR spectral experiments in addition to C isotopic labeling, and structural studies are reported.
