Abstract: The reaction of P-chloro-benzo-1,3,2-dioxaphospholane with diethylamine, (S)-( – )-α-phenylethylamine and (1R,2S,5R)-( – )-menthol afforded the corresponding amino- and cycloalkoxy derivatives. The P-(diethylamino)- benzodioxaphospholane was converted to the corresponding platinum complex of cis-PtL2Cl2 type. It was observed that under not strictly anhydrous conditions, one of the benzodioxaphospholane rings suffered ring opening. The stereostructures and the relative energies of the dioxaphospholane-related platinum complexes were calculated by the B3LYP/6-31G* – LANL2DZ, as well as the PM6-DH methods. The phenylethylamino- and menthylbenzodioxaphospholanes were stabilized as the corresponding P-boranes. Decomplexation of a few P-boranes was studied and the optimum conditions were evaluated.
