We report mesoporous nano-Pd-MCM-41 catalyzed rapid and efficient synthesis of 1,3,5-triarylbenzenes via de-nitrative cyclotrimerization of β-nitrostyrenes. All the reactions were very fast and high yielding. The Pd-MCM-41 was also very effective in catalyzing de-nitrative [3+2] cycloaddition of β-nitrostyrenes with TMSN3 to synthesize 4-aryl-NH-1,2,3-triazoles. The catalyst was reused at least up to eight times with minimum loss of catalytic activity.

A ZrCl4-mediated simple method for the conversion of vinyl nitrates to 1,2,3-triazoles in excellent yields is developed. The obtained new triazoles were evaluated for their antimicrobial activity.

Catalytic activity of copper(II) 1,3,5-benzenetricarboxylate, HKUST-1, in reactions of condensation of aromatic aldehydes with nitromethane was studied. It was shown that HKUST-1 catalyzed condensation of salicylaldehyde with nitromethane leading to formation of trans-nitrovinylphenol, while 9-anthracenecarbaldehyde did not react in the same conditions. Catalytic activity of HKUST-1 was consistent with its sorption capacity in respect to the reagents. The difference in catalytic activity of HKUST-1 in reactions with salicylaldehyde and 9-anthracenecarbaldehyde can be caused by sieving effect (molecules discrimination by size). Kinetics of salicylaldehyde condensation with nitromethane, catalyzed by HKUST-1, as well as kinetics of salicylaldehyde sorption by HKUST-1 were studied. Accessibility of pores of HKUST-1 to salicylaldehyde and condensation product (trans-nitrovinylphenol) was evaluated by molecular mechanics. Catalytic activity (reaction rate and salicylaldehyde diffusion rate) of HKUST-1 is compared with FeIII analog, role of diffusion rate is shown.

The development of fluorogenic probes for chemical transformations bearing anthracene as a fluorescent core moiety is reported. Fluorogenic probes were designed by linking anthracene with functional groups used for reactions of interest. Each fluorogenic probe, possessing a reaction group such as aldehyde, α,β-unsaturated ketone, or imine at the 9-position of the anthracene, showed no or very low fluorescence. Reaction products of the probes, including aldol and addition products, were highly fluorescent. The products showed more than 1000-fold higher fluorescence than did the fluorogenic probes under the same conditions. The utility of the fluorogenic probes was demonstrated in monitoring the progress of a catalyzed aldol reaction.
