Abstract
(EN)
New racemic, optically active phosphorus compounds have the formula (I), in which R stands for lower alkyl, lower alkoxy or a protected hydroxy group; R1 stands for lower alkoxy, phenoxy, benzyloxy, chlorine or bromine; R2 stands for lower alkyl or lower alkoxy and n equals 0, 1 or 2. These compounds represent precious intermediates for the production of known as well as new diphosphine ligands.
