Acetals from primary alcohols with the use of tridentate proton responsive phosphinepyridonate iridium catalysts

The association of the new phosphinepyridonate ligands along with an iridium metallic precursor resulted in the selective acetalization of various primary alcohols via a formal dehydrogenative coupling reaction.

Versatile bonding and coordination modes of ditriazolylidene ligands in rhodium(iii) and iridium(iii) complexes

Metalation of novel ditriazolium salts containing a trimethylene (–CH₂CH₂CH₂–) or dimethylether linker (–CH₂OCH₂–) was probed with different rhodium(iii) and iridium(iii) precursors.
