<p>New organic compounds of phosphorus, comprised of hetero-phospha-cycloalkanes of which the phosphorus atom forms a complex with a borane. They may be prepared by the action of one borane on a hetero-phospha-cycloalkane, within a solvant, between -20°C and +60°C. Their transformation into other derivatives, particularly into phosphinates or phosphines may take place without loss of the chirality of the initial complex. A particular useful application is their conversion into phosphines which are optically very active and used particularly as catalysts in various reactions.</p> |
