Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya published new progress about 14284-06-1. 14284-06-1 belongs to copper-catalyst, auxiliary class Copper, name is Copper(II) ethylacetoacetate, and the molecular formula is 0, Safety of Copper(II) ethylacetoacetate.

Kondrat’ev, P. N. published the artcileReaction of polyfluorinated copper(II) β-diketonates and β-keto esterates with hydrazines, Safety of Copper(II) ethylacetoacetate, the publication is Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya (1990), 640-5, database is CAplus.

Treating copper(II) β-diketonates I [R = Me, CF3, CF3(CF2)5; R1 = Me] with NH2NH2.2HCl in H2O containing NaOH gave 72-86% pyrazoles II (same R, R1; R2 = H). Similar reaction of I (R = R1 = CF3) gave 20% II (R = R1 = CF3; R2 = H). Reaction of β-keto esterates I [R = CHF2, CF3, CF3(CF2)3, Me, H(CF2)4; R1 = OEt] with R2NHNH2.xHCl (R2 = H, x = 2; R2 = Ph, x = 1) in EtOH containing NaOH gave 20-61% pyrazoles II (same R; R1 = OH; R2 = H, Ph). The structure of II [R = H(CF2)4, R1 = OH, R2 = Ph] was determined by x-ray crystallog.
