    摘要: The invention relates to compounds having a structural element of formula (I) in an aromatic hydrocarbon ring, wherein: M represents -Li, -MgX3, (C1-C18-Alkyl)3Sn-, -ZnX3 or -B(O-C1-C4-Alkyl)2; X1 and X2, independent of one another, represent O or N, and C-bound hydrocarbon radicals or heterohydrocarbon radicals are bound to the free bonds of the O and N atoms; group -C=C-, together with C atoms, forms a hydrocarbon aromatic compound and represents X3 Cl, Br or I. The inventive compounds are easily obtained by directly substituting the hydrogen in the ortho position to the P atom with metalation reagents. The metal atoms can then be substituted by a reactive electrophilic compound. The group -P(X1-)(X2-)----(BH3)0,1 can then be converted into a secondary phosphine group. The inventive method enables the production of monophosphines and diphosphines even on a large scale, which are valuable ligands for metal complexes serving as catalysts for, e.g. enantioselective hydrogenations.

Die Metallatome können dann durch reaktive elektrophile Verbindung substituiert werden. Die Gruppe -P(X 1 -)(X 2 -)----(BH 3 ) 0,1 kann dann in eine Sekundärphosphingruppe umgewandelt werden. Mit dem Verfahren können auch im grösseren Massstab Mono- und Diphosphine hergestellt werden, die wertvolle Liganden für Metallkomplexe als Katalysatoren für zum Beispiel enantioselektive Hydrierungen sind.

    摘要: The present invention relates in a first aspect to a process for hydrogenation of ketones having at least a carbon-carbon double bond in the y, 8 - position to the keto group by hydrogen in the presence of at least one chiral iridium complex of formula (I), where R1 represents a group of formula (II) or (III) or (IV). It has been shown that this process leads to a strong increase in preferential formation of a single isomer. The process is particu larly su itable for the hydrogenation of y, 8 - unsaturated ketones which can be used as flavours and fragrances or for the preparation of vitamin E and its derivatives or of flavours and fragrances.
