摘要: The transient titanium alkylidyne complex (PNP)Ti⋮CtBu (PNP = N-[2-P(CHMe2)2-4-methylphenyl]2-), prepared from α-hydrogen abstraction of the corresponding alkylidene−alkyl species (PNP)TiCHtBu(CH2tBu), can readily undergo intermolecular 1,2-addition C−H bonds benzene and SiMe4. Synthesis reactivity, isotopic labeling, kinetics, theoretical studies strongly favor an pathway α-H step to be rate-determining step.
