Spectral evidence for a photoactivated metallotropy, Recommanded Product: Copper(II) ethylacetoacetate, the publication is Journal of Organometallic Chemistry (1979), 173(2), 211-20, database is CAplus.

UV irradiation of I (R, R¹ = e.g., Me, OEt; PhCH₂, OEt; Ph, Me) (21 compounds) causes a rapid shift of the chelate-enolate-carbeniate equilibrium to the enolate and carbeniate forms. Practically the same amounts of the metallotropic forms were detected by IR spectra after 8 h of UV irradiation and after 100 days without UV irradiation

The effect was studied of the different amounts of addition of Cu complex of acetoacetic ester (P-9) to Cu acetylacetonate (P-8) on the ice-forming activity of P-8 over the temperature range -10 to -20°. The P-8: P-9 ratio was maintained at 3:1, 1:1, 1:3, and 1:6. The total number of ice crystals formed (In) increased, in mixtures containing ≤75% P-9, at temperatures more than -15°. The addition of a hygroscopic component improved the yield of ice crystals formed by 30 times.

The catalytic activity of copper bis(Et acetoacetate) (I) [14284-06-1] in the polymerization of 4,4‘-diphenylmethane diisocyanate  [101-68-8] with poly(ethylene glycol) (II) [25322-68-3] decreases with the growth in II mol. mass due to the reduced concentration of OH-OH-type associates and the increased contribution of O atoms of the glycol ether groups into complex formation with I. The activating influence of I depends on the stability of its complex with glycol. The activity of amine-epoxide catalysts in isocyanate cyclotrimerization was also discussed.
