Ni-catalysed acceptorless dehydrogenative aromatisation of cyclohexanones enabled by concerted catalysis specific to supported nanoparticles [PDF]
Nature CommunicationsThe dehydrogenative aromatisation of cyclohexanone derivatives has had a transformative influence on the synthesis of aromatic compounds because functional groups can be easily introduced at desired positions via classic organic reactions without being ...

The first example of amine-induced reversal of diastereoselectivity in acylation of some trans-2-substituted cyclohexanols [PDF]
ARKIVOC, 2012 The reaction between racemic acyl chlorides and racemic trans-2-substituted-cyclohexanols proceeds diastereoselectively. We found for the first time that addition of a tertiary amine not only accelerates the acylation, but for some substituents leads to ...

Acylation of trans-2-substituted cyclohexanols: the impact of substituent variation on the pyridine-induced reversal of diastereoselectivity [PDF]
ARKIVOC, 2015 Numerous methods for the stereoselective synthesis of chiral compounds exist in the literature, which use chiral templates or catalysts. Only in a limited number of cases have achiral catalysts been shown to significantly influence the stereochemical ...

Oxygen-doped carbon-supported palladium nanoparticles boost the tandem hydrogenation–acetalization–hydrogenolysis of phenols and diphenyl ethers to cyclohexyl ethers [PDF]
Nature CommunicationsThe one-pot hydrotreatment of phenols to cyclohexyl ethers is crucial but difficult to achieve for fine chemical synthesis owing to the easy overhydrogenation to cyclohexanols over traditional metal–acid bifunctional catalysts.
