Fourteen 8 membered phosphorus heterocycles have been synthesised and characterised.Several of them contained sulphur or nitrogen atom also, located four bonds apart from phosphorus.From chemical shifts and 3JPOCH and 3JH-H values, a mobile equilibrium between two conformations is suggested for these compounds.Infrared studies suggest transannular interaction between phosphorus and the hetero atom (S or N).
