Abstract: The prepn. of 1-(Hetero)aryl-3-hydroxy-pyrazoles of formula (I) comprises mixing propiolic acid esters of formula R1C IDENTICAL CCOOR' (II) with (hetero)arylhydrazine derivs. of formula RNHNH2 (III) in an inert solvent; and then treating with a base at 0-60 degrees C. R = opt. substd. aromatic or heteroaromatic; n = 0, 1 or 2; R1 = a gp. which is stable under the reaction conditions; R' = alkyl, cycloalkyl or aryl.

Abstract: A solid (I) containing aluminIum oxide (Al2O3) is claimed, which is obtained by a process comprising contacting Al2O3 precursor(s) (II) with template compound(s) in a liquid medium, in which the template is a dendrimeric molecular nano-system (III) or mixture of 2 or more of these. Also claimed are: (i) the method of producing (I) in this way; and (ii) the use of (III) as template in the production of (I). Preferably The nano-system contains a nitrogen (N), phosphorus (P) or carbon (C) atom or a mixture of 2 or more of these as branch point. (I) also contains element(s) selected from sodium, potassium, calcium, magnesium, beryllium, boron, gallium, indium, silicon, germanium, tin, lead, bismuth, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese, rhenium, iron, cobalt, nickel, ruthenium, copper, zinc, cadmium, mercury and cerium.
