An efficient and simple method for selective oxidation of secondary alcohols and oxidation of alkanes to ketones is reported. An insitu prepared catalyst is employed based on manganese(II) salts, pyridine-2-carboxylic acid, and butanedione, which pro

International audience; Controlling the unidirectional rotary process of second-generationmolecular motors demands access to these motors in their enantiomerically pure form. In this paper, we describe an enantioselective route to three new second-ge

Light-driven rotary molecular motors based on overcrowded alkenes can be substituted with electron-donating and electron-withdrawing substituents ( R = OMe, Cl and CN) in direct conjugation with the central double bond ( the axis of rotation) without

Publikováno v: Advanced Functional Materials, 17(5), 718-729. WILEY-V C H VERLAG GMBH

One of the key challenges in taking light-driven unidirectional rotary motors from discovery to application is to increase the rate of rotation. Herein, we review our ongoing efforts to address this issue by meticulous improvement to the molecular de
