Efficiency of poly(N-vinylimidazole) as the basic recyclable catalyst for the Michael addition of CH-acids to acrylonitrile, methyl acrylate, methyl vinyl ketone and methyl vinyl sulfone in water at ambient temperature was studied. In these reactions, formation of both 1 : 1 and 1 : 2 adducts is possible.

Chemiluminescence was observed in ferrocene-catalyzed decomposition of bridged 1,2,4,5-tetraoxanes, namely, 2,3,5,6-tetraoxabicyclo[2.2.1]heptanes. The chemi- and photoluminescence spectra revealed the main products and luminescence emitters to be β-diket
