Abstract

L'extension de la réaction de Todd aux 1-hydrido-1-organyloxybicyclophosphoranes 2–5 porteurs d'un groupe amine secondaire conduit à des bis(bicyclophosphoranes) cycliques 2d–5d ainsi qu'à des bicyclophosphoranes symétriques 6, 7, 8 dans lesquels l'hydrogène lié à P a été remplacé par le reste organyloxy. Ces derniers composés constituent d'excellents synthons pour la synthèse de macrocycles bicyclophosphoraniques originaux.

Mots-clés: Hydridobicyclophosphoranes; réaction de Todd.

The extension of the Todd reaction to 1-hydrido-1-organyloxybicyclophosphoranes 2–5 bearing a secondary amine group leads to a cyclic bis(bicyclophosphoranes) 2d–5d as well as to a symmetric bicyclophosphoranes 6, 7, 8 in which the H—P atom has been substituted by the organyloxy group. These last compounds are a good synthons for the preparation of new bicyclophosphoranes containing macrocycles.
