Some new spirocycles of pentacoordinated antimony are described. By means of the temperature-dependent proton-resonance spectra of the antimony penta- organyls (XXXV) and (XXXVI) conclusions concerning the dynamic stereochemistry of these derivatives are possible. The cyclic stibines, essential for the synthesis of the pentavalent antimony derivatives, are prepared by a new method with the aid of bidentate
