“…The identity of the compounds obtained was confirmed by physicochemical method and by MS spectrometry. The physicochemical and spectral data of all compounds obtained ( 17 – 20 , 23 – 27 , 29 – 31 ) have been confirmed by literature data [ 34 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ]. The identities of compounds 17 , 21 – 23 and 28 were confirmed by additional spectral analysis.…”

Increasingly stringent regulations aimed at protection of the natural environment have stimulated the search for new synthetic methodologies in organic and medicinal chemistry having no or minimum harmful effect. An interesting approach is the use of alternative activation factors, microwaves (MW) or ultrasounds (US) and also their cross-combination, which has been tested in the fast and efficient creation of new structures. At present, an easy and green hybrid strategy (“Lego” chemistry) is generally recommended for the design of new substances from different chemistry building blocks. Often, selected biologically active components with specific chemical reactivities are integrated by a suitably designed homo- or heterodifunctional linker that modifies the functionality of the starting structure, allowing easy covalent linkage to another molecule. In this study, a fast introduction of heterodifunctional halogenoacidic linker to selected mono-, di- and triphenolic active substances, allowing their functionalization, was investigated. Nucleophilic substitution reaction was chosen to produce final ethers with the reactive carboxylic group from phenols. The functionalization was performed using various green factors initiating and supporting the chemical reactions (MW, US, MW-US). The benefits of the three green supporting methods and different conditions of reactions were analyzed and compared with the results of the reaction performed by conventional methods.

“…The large bathochromic shifts in compound 1 indicate that the functional groups of ligand are effectively interacting with the metal ions [45]. Similar bathochromic shifts are observed also in other polymeric compounds [46]. In addition, the fluorescence spectrum of compound 1 in the peak profile is indicative of the slight influence of the coordination geometry of strontium ions and coordination modes of HSIP 2 À ligands on the electronic structures.…”

A new tetranuclear organotin carboxylate {[(n‐Bu2SnO)2L]2}n (complex 1) was synthesized by the reaction of di‐n‐butyltin oxide with (p‐carboxymethoxy‐phenoxy) acetic acid (LH2) and characterized by elemental analyses: IR, UV–visible, 1H, 13C, 119Sn NMR spectroscopy and single crystal X‐ray study. X‐ray crystallography diffraction data revealed that the complex 1 was polymeric fashion with a chain structure containing a ladder‐like tetranuclear organo‐oxotin cluster. In the complex 1, the ligand LH2 is coordinated to the central tin(IV) atoms via the carboxylato‐O atoms. The tetranuclear tin system is formed by the bridges through the carbonyl oxygen atom of the carboxylate moieties and making the tin atom of pentacoordinated in distorted trigonal bipyramidal geometry. Single crystal X‐ray data indicate that the complex 1 crystallized in the cubic system with the space group C2/c.
