Abstract
Bromodiphosphine oxide 3 was obtained from the selectively protected chiral diol 2 by the double [2.3]-sigmatropic shift of an intermediate phosphinit e. The bromophosphine oxide derivative 3 was converted by radical cyclisati on into rigid bicyclic diphosphine 1. The diphosphine 1 was characterised a nd tested as a ligand in several metal catalytic reactions. (C) 2001 Publis hed by Elsevier Science Ltd.
