Experiments and microkinetic modeling were used to investigate the reaction mechanism of cis-cyclooctene oxidation with H2O2 on heterogeneous manganese 1,4,7-trimethyl-1,4,7-triazacyclononane (Mn–tmtacn) catalysts. A mechanism based on literature r

Immobilizing a homogeneous catalyst provides obvious handling benefits, but ideally can also enhance catalyst productivity or selectivity because of beneficial interactions between the surface and the active site. Here, Mn 1,4,7-trimethyl-1,4,7-triaz

Manganese complexes of 1,4,7-trimethyl-1,4,7-triazacyclononane (tmtacn) are highly active and selective alkene oxidation catalysts with aqueous H(2)O(2). Here, carboxylic acid-functionalized SiO(2) simultaneously immobilizes and activates these compl

The crystal structure of Na[Co(NC6H6O6)] · H2O is reported. The structure is compared to similar transition-metal nitrilotriacetate complexes containing different alkali cations and transition metals (Cu2+ and Zn2+). Inner-sphere coordination of the

A unique method has been developed to synthesize an active heterogeneous oxidation catalyst by the in situ grafting of a 1,4,7-trimethyl-1,4,7-triazacyclononane manganese complex on carboxylic acid-functionalized supports serving dual roles as surfac
