Title
(DE) DIPHOSPHONSAURE DERIVATE ALS ZWISCHENPRODUKTE IN DER HERSTELLUNG VON DIPHOSPHINLIGANDEN
(EN) DIPHOSPHONIC ACID DERIVATES AS INTERMEDIATES FOR THE PRODUCTION OF DIPHOSPHINE LIGANDS
(FR) DERIVES D'ACIDE DIPHOSPHONIQUE UTILES COMME PRODUITS INTERMEDIAIRES LORS DE LA PREPARATION DE LIGANDS DIPHOSPHINIQUES
Abstract
(DE)
Es werden neue, racemische und optisch aktive Phosphorverbindungen der Formel (I) beschrieben, worin R niederes Alkyl, niederes Alkoxy oder eine geschützte Hydroxygruppe bedeutet, R1 niederes Alkoxy, Phenoxy, Benzyloxy, Chlor oder Brom bedeutet, R2 für niederes Alkyl oder niederes Alkoxy steht und n die Zahl 0, 1 oder 2 darstellt. Diese Verbindungen sind wertvolle Zwischenprodukte in der Herstellung sowohl bekannter als auch neuer Diphosphinliganden.
(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.
(FR)
De nouveaux composés racémiques et optiquement actifs de phosphore ont la formule (I), dans laquelle R représente alkyle inférieur, alcoxy inférieur ou un groupe hydroxy protégé; R1 représente alcoxy inférieur, phénoxy, benzyloxy, chlore ou brome; R2 représente alkyle inférieur ou alcoxy inférieur et n vaut 0, 1 ou 2. Ces composés constituent des produits intermédiaires précieux pour la préparation de ligands diphosphiniques aussi bien connus que nouveaux.
