Cleavage of N ‘,N ‘-Dialkylhydrazides with PhI(OH)OTs
摘要:
[GRAPHICS]N',N'-Dimethylhydrazides are efficiently cleaved to give the carboxylic acid upon treatment with Phl(OH)OTs in water or water/CH2Cl2 mixtures, The reaction occurs with the evolution of a gas.

taking a first-principles approach guided by computation, these new mediators were identified and rapidly expanded into a library using ubiquitous buildingblocks and trivial synthesis techniques. The ylide-based approach to C–H oxidation exhibits tunable selectivity that is often exclusive to this class of oxidants and can be applied to real-world problems in the agricultural and pharmaceutical sectors

Tetrazans are the main products of the action of sulphurmonochloride on 2-acyl-1,1-dimethylhydrazines. In some cases 1,3,4-oxadiazoline-2-thiones are also formed, in smaller yields.

The [M(HL)(2)(H2O)(2)]X-2 complexes were synthesized(M = Mn(II), Co(II), Ni(II), Cu(II), Zn; X = CH3COO-, Cl-, BF4-) that incorporate bidentately coordinated molecules of N,N-dimethylhydrazide of 4-nitrobenzoic acid (HL). The latter molecules chelate the metal atom through the carbonyl O atom and the N atom of dimethylamino group. The square-planar complexes of Cu and Ni with deprotonated form of a ligand with composition ML2 were also isolated. The synthesized complexes were studied by IR, electronic and EPR spectroscopies, and by cyclic voltammetry.
