The alpha-effect can be used in the acceleration of the Diels-Alder reaction between a series of dienes and electron deficient dienophiles using iminiumion catalysis, providing a novel molecular scaffold capable of performing this class of catalytic process.

N′-Propylhydrazide analogs of hydroxamic inhibitors of histone deacetylases (HDACs), including tubastatin A, vorinostat and belinostat, were synthesized. All prepared compounds inhibited HDAC1/2/3, but not HDAC6, except for one hydrazide analog of HDAC4/5/7 inhibitor that was completely inactive. A novel 4-substituted derivative of N′-propylbenzohydrazide with extremely high anti-HCV activity was discovered.
Reactions of molybdenum oxo-complexes with substituted hydrazines. Part 1. The preparation of molybdenum alkyl- and aryl-imido-complexes; the crystal and molecular structure of (N-benzoyl-N′-p-tolyldiazene-N′O)dichloro(dimethylphenylphosphine)(p-tolylimido)molybdenum

The molybdenum(IV) oxo-complexes [MoOCl2(PR″3)3](PR″3= PMe2Ph or PEt2Ph) react with the substitutedhydrazines RCONHNHR′(R = Ph, p-ClC6H4, p-MeC6H4, p-MeOC6H4, Et, Prn, Pri, or CH2Ph; R′= Ph, p-ClC6H4,p-MeOC6H4, 1-C10H7, or Me) to give the imido-complexes [MoCl2(NR′)(R′N2COR)(PR″3)]. The crystal and molecularstructure of the title complex has been determined from single-crystal X-ray diffractometer
