Preparation of new 1,2-disubstituted ferrocenyl stibine derivatives containing ether/thioether pendant arm from a quaternary ferrocenyl ammonium salt

摘要

New 1,2-disubstituted ferrocenyl stibines viz. containing -CH2OR or -CH2SR pendant arm at the orthoposition have been synthesized and characterized by various physicochemical methods. These new ferrocenylstibines were prepared by the nucleophilic substitution reaction of diphenyl[(N,N,N-trimethylaminomethylferrocenyl)iodide]stibine by different phenols and thiol viz. o-salicyldehyde, m-hydroxyacetaphenone, o-hydroxyaceta-phenone and furan-2 ylmethylthiol. Molecular structures of stibines (2),(3),(4) and (5) have been determined by X-ray crystallography. Molecular structures show that none of these heterobimetallic compounds possess hypervalent interaction in the solid state. This type of interaction was found in similar compounds with CH2NR2 pendant arm.
