资源简介：
The reactivity of the oxalamide-based carbene 2 was investigated. Treatment with styrene or methylacrylate proceeded
under carbene addition to yield the respective cyclopropanation products 6a,b. With elemental selenium the selenide 7 was obtained, which was characterized by X-ray diffraction.
The Rh complex [(COD)RhCl(2)] (10) was also
structurally characterized. From the IR spectrum of the dicarbonyl
derivative [(CO)2RhCl(2)] (11) a Tolman electronic parameter of 2068 cm–1 was
calculated for the diamidocarbene 2, which characterizes
this ligand as the least electron donating NHC known so far. The dimerization
product of carbene 2, the intensly fluorescing tetraamido
ethylene 3, showed an unexpected chemical stability.
Treatment of the chloro compound 1a with methanol afforded
the methoxide 5a, whose structure was determined by X-ray
diffraction.
