Embodiment Construction

[0076] General Practice

[0077] All preparations described below were performed under inert gas using standard vacuum line techniques. The solvents were dried over a suitable desiccant before use (Purification of Laboratory Chemicals, W.L.F. Armarego (Author), Christina Chai (Author), Butterworth Heinemann (Elsevier), Sixth Edition, Oxford 2009).

[0078] Phosphorus trichloride (Aldrich) was distilled under argon before use. All preparative operations are performed in heated vessels. The product is characterized by NMR spectroscopy. Chemical shifts (δ) are expressed in ppm. 31 PNMR signal reference: SR 31P =SR 1H *(BF 31P / BF 1H )=SR 1H *0.4048 (Robin K. Harris, Edwin D. Becker, Sonia M. Cabralde Menezes, Robin Goodfellow and Pierre Granger, Pure Appl. Chem., 2001, 73, 1795-1818; Robin K. Harris, Edwin D. Becker, Sonia M. Cabralde Menezes, Pierre Granger, Roy E. Hoffman and Kurt W. Zil Pure Appl. Chem., 2008, 80, 59-84).

Abstract

The invention relates to a monophosphites comprising an anthrol. The invention also relates to an application of the monophosphites as a ligand in hydroformylation. The invention also claims a protection for a method, wherein the monophosphites are used for catalyzing hydroformylation of an olefin to an aldehyde.

Description

technical field [0001] The present invention relates to monophosphites with anthracenol. The invention also relates to their use as ligands in hydroformylation. Background technique [0002] The reaction between olefinic compounds, carbon monoxide and hydrogen in the presence of a catalyst to form aldehydes with one more carbon atom is known as hydroformylation or oxo synthesis. The catalysts used in these reactions are common compounds of transition metals of Group VIII of the Periodic Table of the Elements. Known ligands are, for example, compounds from the class of phosphine, phosphite and phosphonite, each bearing trivalent phosphorus P(III). A good review of the current state of hydroformylation of olefins can be found in B. CORNILS, W.A. HERRMANN, "Applied Homogeneous Catalysis with Organometallic Compounds", Vol. , Chem. Rev., 2012, DOI: 10.1021 / cr3001803. [0003] Each catalytically active composition has its specific benefits. Therefore, different catalytically...
