catalyst, which was thoroughly characterized by means of EDS, SEM, TEM, XRD, XPS, and FT‐IR, revealed excellent catalytic activity for the reaction of diphenyl phosphinamide with benzylalcohols through borrowinghydrogenstrategy and acceptorless dehydrogenation with wide functional group tolerance. Moreover, this POP−Ir catalyst could be simply recovered and reused for at least five times without a significant

The instant invention pertains to hindered amine compounds having at least two nitrogen atoms with different basicity. One part is substituted on the N-atom by alkoxy moieties and the other part is substituted on the N-atom by a hydroxy-alkyl moiety. These materials are particularly effective in stabilizing polymers, especially thermoplastic polyolefins, against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are also particularly effective in stabilizing acid catalyzed and ambient cured coatings systems.

We have synthesized novel organoiridium(III) antimicrobial complexes containing a chelated biguanide, including the antidiabetic drug metformin. These 16- and 18-electron complexes were characterized by NMR, ESI-MS, elemental analysis, and X-ray crystallography. Several of these complexes exhibit potent activity against Gram-negative bacteria and Gram-positive bacteria (including methicillin-resistant
