Synthesis of unsymmetrical ureas and S-thiocarbamates under catalyst-free conditions in a [BMIM]BF4 ionic liquid

Unsymmetrical ureas and Sthiocarbamates were prepared in good to excellent yields by direct condensation of phenylurea with amines and thiols in 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF4) without the addition of any additives. The [BMIM]BF4 ionic liquid is a mild medium and can be recycled and reused several times.

New heterocyclic polymers with vicinal parabanic structures

The paper deals with the study of heterocyclization via the cyclocondensation reaction of some reactive polymers by using oxalyl chloride. A few polymers and model compounds were synthesized by the polyaddition reaction of some isocyanates and hydrazine.

Migration of an acyl group in the pyrazole system: Synthesis of 1-acyl-3-hydroxy-1H-pyrazoles and related derivatives. A new preparation of N,N′-diacylhydrazines

A new general method for the synthesis of 1-acyl-3-hydroxy-1H-pyrazoles 5a-f and related derivatives 5g-i starting from 4-ethoxymethylene-2-phenyloxazol-5(4H)-one (1) and hydrazides, 4-phenylsemicarbazide, 4-phenylthiosemicarbazide and benzyl carbazate in boiling dioxane is described. The method includes a migration of an acyl or related unit. The X-ray study and NMR spectroscopic examination confirmed the structure of the products. A one-pot synthesis of N,N′-diacylhydrazines from hydrazides by the assistance of oxazolone 1 is also presented.
