A simple and efficient method for solvent free "dry" state transformation of acid hydrazides 1 to corresponding N,N′ -diacylhydrazines 2 using copper(II) acetate under microwave irradiation has been described. The products are obtained in good yields and excellent purities.

experimental part, p. 126 - 128 (2011/03/21)
A highly efficient and practical methodology for the transformation of acid hydrazides 1 to N,N′-diacylhydrazines 2 is described under solid state conditions at RT utilizing inexpensive and easily available reagent Hg(OAc) 2. The products are obtained in good yields with high purity.

Some known hypervalent iodine(III) mediated reactions, viz (i) dimerization of acid hydrazides 1a-i, (ii) α-tosyloxylation of acetophenones 3a-f, and (iii) α-hydroxylation of acetophenones 3c,d,f have been effected in solid-state.

Hypervalent iodine oxidation of p-substituted benzohydrazides (1a-h), phenylacetohydrazide (1i) and heterocyclic acid hydrazides (1j-l) using one equivalent of iodobenzene diacetate in dry dichloromethane or acetonitrile leads to dimerization thereby providing a new and facile method for the synthesis of N,N-diacylhydrazines 2.

, p. 543 - 546 (2007/10/02)
3-Substituted 1,2,3-benzotriazin-4(3H)-one 1-oxides are formed on peracid oxidation of 3-alkyl- and 3-methoxy-1,2,3-benzotriazin-4(3H)-ones. The 3-(a-alkoxyalkyl) 1-oxide derivatives could be dealkylated to the tautomeric 3-unsubstituted compound. The acidities of the isomeric N-oxides of the 1,2,3-benzotriazinone system are compared. Phenyl iodosodiacetate converts o-nitrobenzaldehyde benzyl- and phenyl-hydrazones into the 2-substituted 4-oxido-1,2,3-benzotriazine1 -oxide betaines(1).
Substitution Reactions of Phenylated Aza-heterocycles. Part 1. Nitration of 2,5-Diphenyl-1,3,4-oxadiazole: a Product Study using High Performance Liquid Chromatography
Blackhall, Alexander,Brydon, Donald L.,Saga, Anthony J. G.,Smith, David M.
, p. 773 - 777 (2007/10/02)
Contrary to a previous literature report, nitration of 2,5-diphenyl-1,3,4-oxadiazole (1) under various conditions gives a mixture of all six possible 2,5-bisnitrophenyl derivatives, which may be analysed quantitatively using high performance liquid chromatography.Nitration using nitric acid alone gives mainly the three isomers with p-nitrophenyl groups, i.e. (7), (9), and (10), whereas mixed acids and nitronium tetrafluoroborate give mainly meta-nitration products, i.e. (6), (8), and (9).Nitration of the three 2-(nitrophenyl)-5-phenyl-1,3,4-oxadiazoles also shows considerable variation of product ratio according to the conditions.
