Аннотация: Reaction of nickel cluster Ni9(HOOCCMe3) 4(?4-OH)3(?3-OH) 3(?n-OOCCMe3)12 (1) or cobalt pivalate polymer [Co(OH)n(OOCCMe3)2-n] x (7) with bis[3,5-(dimethylpyrazolyl)]-1,2,4,5-tetrazine (3) in MeCN solution was found as a result in the formation of isostructural pentanuclear clusters of composition M5(?3-OH) 2(?-OOCCMe3)4(?-N,N?,N? -3,5-Me2C3HN2C2(O)N 4)4(MeCN)2 (M = Ni (4), Co (8)) with a planar spirane metal core. Reaction of cobalt complex 7 with 3 in benzene gives rise to a pentanuclear cluster Co5(?3-OH)2(?-OOCCMe 3)4(?-N,N?,N?-3,5-Me2C 3HN2C2(O)N4)4(C 5N2H8)2 (9), containing coordinated pyrazole molecules as terminating ligands instead of labile MeCN ligands in 8. The reaction of cluster 8 with 2,6-diaminopyridine (T = 85 °C) in MeCN results in the substitution of MeCN ligands and formation of a new cluster Co5(?3-OH)2(?-OOCCMe3) 4(?-N,N?,N?-3,5-Me2C3HN 2C2(O)N4)4(C5H 7N3)2 (10) with two 2,6-diaminopyridine ligands instead of MeCN molecules. The reactions of 4 and 8 with NiCl 2·6H2O in MeCN/EtOH solution (3: 1) give rise to isostructural ferromagnetic pentanuclear chloro-bridged clusters M 5(?3-OH)2(?-CI)2(? -OOCCMe3)2(?-N,N?,N?-3,5-Me 2C3HN2C2 (O)N4) 2(?-N,N?,N?,O-3,5-Me2C3HN 2C2(O)N4)2(MeCN)2 (M = Co (11), Ni (12)). The reaction of 8 with solid COCl2·6H 2O in MeCN results in new seven-nuclear ferromagnetic cluster CO 5(?3-OH)2(?-CI)2(? -OOCCMe3)2(?-N,N?,N?-3,5-Me 2C3HN2- C2(O)N4) 2(?-N,N?,N?,O-3,5-Me2C3HN 2C2(O)N4)2(MeCN) 2[Co(CH3CN)CI2]2 (13). The molecular structures of 4, 8, 9, 10, 12 and 13 established by X-ray diffraction studies and magnetic behavior of new nickel and cobalt pivalate clusters are discussed.

CARBORANES -- C-C COUPLING -- PHTHALAZINE-N-OXIDE
Аннотация: An original transition metal-free approach based on the direct CC coupling of phtalazine-N-oxide with the carboranyl anion has been developed. A series of the novel C-modified closo-carboranes such as 1-(2-oxido-3-acyl-3,4-dihydrophtalazinyl-4-yl)-1,2-dicarba-closo-dodecaboranes and 1-(2-formylbenzyl)-1,2-dicarba-closo-dodecaborane have been obtained. The synthesized boron clusters could be of interest as promising building blocks in design of BNCT delivery agents.

    Azaheterocyclic derivatives of ortho - carborane: synthetic strategies and application opportunities / L. A. Smyshliaeva, M. V. Varaksin, V. N. Charushin, O. N. Chupakhin // Synthesis. - 2020. - Vol. 52, № 3. - P337-352

AZAHETEROCYCLES -- CARBORANES -- CARBORYNE -- CROSS-COUPLING REACTIONS -- DECABORANE
Аннотация: Azaheterocyclic derivatives of 1,2-dicarba- closo -dodeca borane (ortho -carborane) are known to be of particular interest due to numerous plausible applications, particularly, in medicine, materials science, and advanced technologies. Three principal synthetic strategies resulting in azaheterocyclic carboranes, in which boron-enriched and azaheterocyclic fragments are linked to each other, either directly by means of the C-C bonds or through a short spacer (CH 2, CH 2 S, CH 2 O, etc.), have been outlined. These synthetic approaches are of general character and can be used both individually and in combination to afford promising organoboron clusters of diverse architectures. 1 Introduction 2 C-C Cross-Coupling Strategies in the Synthesis of Azahetero cyclic Carboranes 3 Carboryne-Based Transformation Strategies 4 Condensation Strategies: Reactions of Decaborane B 10 H 14 with Substituted Acetylenes 5 Conclusion and Outlook.

    Unusual synthesis of triosmium carbene clusters by tandem activation of chlorohydrocarbons and heterocyclic amines / B. Y. Savkov, V. A. Maksakov, A. V. Virovets [et al.] // European journal of inorganic chemistry. - 2021. - № 10. - P989–996
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The carbene ligand is assembled on a cluster core of two dichloromethane and one morpholine at room temperature, which is the first example of carbene ligands formed in this way. Clusters with a carbene ligand exist as two stable isomers, as confirmed by NMR studies and conformational analysis. Possible mechanistic pathways for the formation of clusters with carbene and enamine ligands are proposed.
