The chemistry of stable metalylenes (the heavier group
14 element
analogues of carbenes) is an intriguing target of main group chemistry
due to their synthetic potential and industrial application. In the
present study, we report on the utilization of an abnormal N-heterocyclic
carbene (aNHC) and a cyclic alkyl-amino carbene (cAAC) as a Lewis
base for the syntheses of compounds aNHC·SiCl2 (3), aNHC·SnCl2 (4), and cAAC·SnCl2 (5). The synthesis of silylene 3 involved the ligand-substitution reaction between NHC·SiCl2 and an aNHC. However, compounds 4 and 5 were synthesized by the reactions of aNHC and cAAC with
SnCl2 in the molar ratio of 1:1. Compounds 3–5 are well-characterized with various spectroscopic
methods and single-crystal X-ray structural analysis.
