Reactions of 3-methyl-1-phenyl-4,6-dihydroimidazo[4,5-c]pyrazole-5(1H)-thione with carbonyl compounds gave the arylidene derivatives 2 and 3, with recinoleic acid, phosphorus oxychloride/phosphorus pentachloride mixture and copper bronze gave the adduct 4, the chloro derivative 5 and the dimer with desulfurization 7. The behaviour of the chloroderivative towards hydrazine and primary amines have also been studied. On the other, reaction of 5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one with aromatic aldehydes gave the arylidene derivatives 8a-d, which on reaction with thiourea gave the pyrazolopyrimidinethione derivatives 9. The behaviour of compounds 9 towards copper bronze, sodium nitrite/acetic acid mixture, acrylonitrile and formaldehyde/ morpholine and its reaction with compound 1 in presence of copper bronze have also been taken into consideration.
