Abstract

Three novel N-acetylated spiro-λ4-sulfanes with five-membered spirorings (fused with aromatic rings) and with two N heteroatoms (in (1)) or with N and O heteroatoms (in (2) and (3)) in axial positions have been prepared and their molecular structures determined by X- ray diffraction. The molecular structures of compounds (1–3) show trigonal bipyramidal geometry about the central sulfur atom. The rather long axial S–N bonds (1.93 Å) in the ...
