Korstanje, Ties J. published the artcileSynthesis and Characterization of Rhenium(V) Oxo Complexes Bearing PNP-Pincer Ligands, Related Products of pyridine-derivatives, the publication is Organometallics (2014), 33(9), 2201-2209, database is CAplus.
The synthesis of pyridine-based PNP-pincer Re-oxo complexes, with Ph (1, 3), tert-Bu (2), or cyclohexyl (4) groups on the P atoms and either a ReO2X (1, 2) or a ReCl2O (3, 4) core is reported. The structures of these compounds were characterized using 1H, 13C, and 31P NMR and using x-ray crystallog. for 1 and 4. Compounds 2 and 3 crystallize as the corresponding ReO(OH)X compounds upon their reaction with moisture during the crystallization process. The complexes were tested as catalysts in the oxidation reaction of limonene with H2O2, the O atom transfer reaction from pyridine N-oxide to PPh3, and the dehydration reaction of 1-phenylethanol, but all showed poor catalytic performance. All complexes can be deprotonated at the benzylic arm, and 2 can be deprotonated twice, accompanied by dearomatization of the pyridine ring. 3 and 4 are highly stable in their oxidized forms. The noninnocent behavior shown here could open up possibilities for cooperative catalysis.
