      The structurally unique (9,10-dihydroxyoctadecyl)trimethylammonium (OH-ODTMA) surfactant is synthesized from oleylamine. The OH-ODTMA, ODTMA, and OLEYL-TMA amphiphiles are successfully intercalated within clay galleries. The amount of gauche conformers is significantly higher in the novel OH-ODTMA organoclay than in the ODTMA intercalate.

      Synthesis of a rare borondihydride complex has been made possible through the use of a relatively strong donor monoanionic bis(phosphinimino)amide ligand. Crucially, the ligand backbone is void of any reactive acidic hydrogen. The same ligand has also made feasible the synthesis of some heteroleptic dihalo derivatives of group 13 elements.

      The soluble diiron monooxygenases (SDIMOs) are a diverse group of enzymes that use a diiron active centre to add oxygen to a wide range of organic molecules. Here we review how natural biodiversity and laboratory mutagenesis studies have revealed how the protein scaffold of SDIMOs controls the activity of the enzymes and the presentation of substrates to the diiron site.

      A tyrosinase model based on the binucleating ligand Lpy2 was developed and characterized. The ligand Lpy2 contains a combination of an imine and a pyridine function in the sidearms that are bridged by a flexible alkyl spacer. The Cu2Lpy2 complex catalyzes the conversion of monophenol DTBP-H into the o-quinone DTBQ (TON = 18). An electron-poor substrate is converted into the semiquinone.
