The reduction of a series of [n](2,7)pyrenophanes (n = 7-10) with lithium or potassium metal shows that the strain in the system, controlled by the length of the tether, determines the nature of the reduction products. The reduction of [7](2,7)pyrenophane (2) and [2]metacyclo[2](2,7)pyrenophane (3) leads to reductive dimerization followed by novel intramolecular sigma-bond formation as a means ...

This paper reports the continuous reductive amination of different molecules, including biomass-related compounds, over carbon-supported FeNi nanoparticles obtained on the basis of inexpensive and abundant metal precursors and cellulose. A biorefinery case study for the preparation of pyrrolidones via acid-catalyzed hydrolysis of glucose followed by reductive amination of the obtained levulinic...

Reductive S-S bond cleavage of a disulfide precursor obtained from a pyridine-catalyzed Peterson-type reaction starting from camphorpyrazole , thionyl chloride and 2-methyl-2-(methyldithio)propionaldehyde yields 2,2'-bis(camphorpyrazol-1-yl)-2-methylpropane-2-thiol (HSiprbpm3cam, ); the first zinc complexes bearing this ligand exhibit kappa3 coordination of the ligand.
