the resulting coordinationpolymers and metal–organic frameworks (MOFs). The monopotassium salts show a decreasing (chemical) stability in water upon heating, as well as a decreasing thermal stability, as evidenced by differential scanning calorimetry/thermogravimetric analysis (DSC/TGA). A similar decreasing thermal stability is found for two series of isostructural coordinationpolymers (UHM-33 topology:

The invention relates to methods for the detection of enzymatic activity, in particular, to in vivo methods. It relates to a non-invasive method for in vivo enzyme activity detection, in particular, activity of proteinases, to substrates specifically developed for these methods and to a device detecting product formation of the enzyme to be tested based on determination of signals produced by the substrates and/or its products.

Reactions of N-fluorobenzenesulfonimide with methylbenzenes, phenols, and phenol ethers were studied under solvent-free conditions. The rate constant ratio for the reactions with mesitylene and durene indicates polar mechanism of the process. Solvent-free fluorination of aromatic compounds with N-fluorobenzenesulfonimide in some cases is more selective than reactions with other N-F reagents in a solvent.
