Isolation and Reactivity of a Chlorogermyliumylidene Featuring Two Ge–Cl Units

Abstract: Deprotonation of 1-mesityl-4,5-diphenyl-2-imidazole 1 with nBuLi, followed by salt metathesis reaction with GeCl 2 ·dioxane complex, led to the formation of the chlorogermyliumylidene 2 bearing two Ge-Cl units, which has been isolated and fully characterized by standard spectroscopic and X-ray diffraction analysis. Structural and NMR spectroscopic data as well as computational studies revealed that the positive charge mainly [a]

“…744 Very recently, Kinjo and co-workers presented an interesting example of the chlorogermyliumylidene 826, featuring two Ge−Cl unuts. 747 This compound displays a puckered boat conformation of the Ge 2 N 2 C 2 ring. In this ring, the C and N atoms are nearly coplanar, whereas the two Ge atoms deviate from this plane.…”

“…38 The 1 H, 13 C, and 19 F NMR spectra were recorded on a JEOL ECA 400 spectrometer. The chemical shifts (δ) are relative to SiMe 4 for 1 H and 13 C, and CFCl 3 for 19 F. The purity of compounds 2 and 3 was characterized by elemental analysis, which was performed by Nanyang Technological University, Division of Chemistry and Biological Chemistry. Melting points were measured in sealed glass tubes and were uncorrected.…”
