The invention relates to novel phosphane ligands of formula (Ia) and (Ib): (adamantyl)nP(alkyl)m(1a); (adamantyl)o(Alkyl)qP (alkylen′)P(adamantyl)r(alkyl)s (1b), wherein adamantyl represents an adamantyl radical (IIa, IIb) bonded to the phosphorous atom in position 1 or 2. The invention also relates to the production and use of the above-mentioned ligands in the presence of transitional metal compounds of the 8th. Subgroup of PSE for catalytic reactions, particularly for the refining of halogen aromatics for producing aryl olefins, dienes, diarylene, benzoic acid and acrylic acid derivatives, aryl alkanes and also amines.

The syntheses of isomeric diadamantylphosphinic acid chlorides are reported. By high-field two-dimensional NMRspectroscopy all proton and carbon-13 signals were identified and assigned unequivocally. Diastereotopism effects and the conformational behaviour of these compounds are discussed.
