Found, that at interaction of acid chlorides of ortho-, peri-, cis- dicarboxylic acids with primary amines are formed appropriate isoimides. A series isoimides of 2,3-dichlorobut-2-enedioic acid was synthesized.
The interaction of 1H-imidazole-4,5-dicarbonitrile, 3-nitro-1,2,4-triazole and 1H-tetrazole which containing one by one proton at two donor atoms and which parted by one covalent bond with crown – ethers of possibility synthesis a neutral crystal supramolecular compounds due to a proton donor properties of aromatic heterocyclic was exhibit.
The product of interaction 1,8-naphthaloylchloride with 4-nitroaniline is N-(4-nitrophenyl)isonaphthalimide, but not similar naphthalimide of a symmetric structure, as was assumed earlier.
The formation of stable complexes of crown – ethers with 1,2- diaminomaleonitrile can be utilised for making containers 1,2-diaminomaleonitrile and is taken into account at modeling operation of self-organizational connatural processes
The nature of protondonor’s moleculas which stabilized in crystal molecular complexes by crown-ethers from equilibrium water solutions of fluorides of zirconium, hafnium, niobium and tantalum is determined by a structure of crown-ethers. The investigation has shown perspective position macrocyclic complexes for extraction of titled compounds from fluorine containing water solutions.
Synthesis of diaquafluorosilicate 18-crown-6 and stabilization pentafluorosilicate hydroxonium with a cis-syn-cis isomer dicyclohehane-18-crown-6 at transport interaction of crown-ethers with fluorosilicic acid can be taken into account as a chemical basis at model operation of self-organizational natural processes.
Invariance of stabilization diaquafluorosilicate by 18-crown-6 and synthesis of a complex pentafluorosilicate of hydroxonium with cis-syn-cis isomer dicyclohehane-18-crown-6 at interaction of crown-ethers with solutions of dioxide of silicon in fluorhydric acid reveal dominant influence of a spatial constitution of crown-ethers on an expedient of a complexing.
The interaction of crown-ethers with HN-protondonor molecules obtained crystalline molecular complexes “host-guest” and found, that depending on linear dimensions and method of steric masking of active centres HN-protondonor molecules various structures crown-ethers can be combined in complexes.
The structure of protonodonor moleculas stabilized in crystalline complexes by crown-ethers from equilibrium water solutions of fluorides of boron, silicon, germanium, tin, is determined by a structure of crown-ethers.
