Reaction of zirconocene–carboryne in situ generated
from
Cp2Zr(μ-Cl)(μ-C2B10H10)Li(OEt2)2 with various alkenes RCHCH2 in refluxing toluene gave the monoinsertion products 1,2-[Cp2ZrCH(R)CH2]-1,2-C2B10H10 (R = aryl) or 1,2-[Cp2ZrCH2CH(R)]-1,2-C2B10H10 (R = alkyl) in good to high isolated
yields with very high regioselectivity, depending on the polarity
of the alkenes. This reaction offered an efficient route to zirconacyclopentanes
with a carborane auxiliary, which can be viewed as a carborane version
of zirconacyclopentanes. They are thermally very stable and chemically
inert toward unsaturated organic molecules such as alkenes, alkynes,
nitriles, CO, and CO2. All complexes have been fully characterized
by various spectroscopic techniques. Some have been further confirmed
by single-crystal X-ray analyses.
