Synthesis, structure, and reactivity of the ferrocene-based N-heterocyclic stannylene [Fe{(η5-C5H4)NC6H3-2,6-iPr2}2Sn]
Abstract The N-heterocyclic stannylene [Fe{(η5-C5H4)NC6H3-2,6-iPr2}2Sn] (1) has been synthesised from SnCl2 and the lithium amide [Fe{(η5-C5H4)NC6H3-2,6-iPr2}2Li2]. Compound 1 is inert towards H2, CO, CO2, and MeI under ambient conditions. Immediate hydrolysis and ammonolysis was observed with H2O and NH3, respectively. While oxidation reactions of 1 with chalcogens (O2, S8, Se8) afforded only intractable material, the reaction with Ph2Se2 cleanly furnished [Fe{(η5-C5H4)NC6H3-2,6-iPr2}2Sn(SePh)2] (2). Compounds 1 and 2 have been structurally characterised by single-crystal X-ray diffraction. Compound 2 exhibits an intramolecular CH⋯Se contact compatible with a weak hydrogen bond.
