Understanding intermolecular C–F bond activation by a transient titanium neopentylidyne: experimental and theoretical studies on the competition between 1,2-CF bond addition and [2 + 2]-cycloaddition/β-fluoride elimination†
Abstract
Complex (PNP)TiCHtBu(CH2tBu) (PNP− = N[2-P(CHMe2)2-4-methylphenyl]2) eliminates H3CtBu to form transient (PNP)Ti
CtBu, which activates the C–F bond of
C[tBu(NC5H3F)](F) (1) and (PNP)Ti
C[tBu(NC5H4)](F) (2), respectively. When (PNP)Ti
CHtBu(CH2tBu) is treated with
