    1,3,7-triazapyrene-based ortho-carborane fluorophores: convenient synthesis, theoretical studies, and aggregation-induced emission properties / L. A. Smyshliaeva, M. V. Varaksin, E. I. Fomina [et al.] // Organometallics. - 2021. - Vol. 40, № 16. - P2792-2807
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A convenient transition-metal-free approach, based on nucleophilic substitution of hydrogen (SNH), for consecutive regioselective C–H functionalization of 1,3,7-triazapyrene scaffolds with carboranyllithium and phenyllithium is reported. The theoretical calculations disclosed highlight key features in the regioselectivity and mechanism of the investigated SNH transformations. The novel 1,3,7-triazapyrene-based ortho-carboranes obtained have large potential in the field of molecular electronics as organic luminophores, which are characterized by the aggregation-induced emission and dual-emission effects.

O-CARBORANE -- METALLACARBORANES -- PHOTOLUMINESCENT
Аннотация: Novel B,N,N-cyclometallated Pt(II) complexes of 2,2'-bipyridin-6-yl carboranes exhibit absorption and emission similar to relative Pt(II) complexes of aromatic C,N,N-ligands: the same transitions but lower intensities. DFT calculations suggest the former emits from the (3)MLCT state while for the latter the mixed (3)ICT-MLCT transitions should be considered

Аннотация: The synthesis of pyridine and bipyridine derivatives of m-carborane via aza Diels–Alder reaction of 1,2,4-triazines with 9-allyl m-carborane and their structural characterization and photophysical properties are described. The products 3- and 4-(m-carborane-9-ylmethyl)-2,2`-bipyridines form Zn(II) complexes on reaction with ZnCl2, which increases significantly their fluorescence intensity.

Ol'shevskaya, V. N. Kalinin, V. P. Krasnov, V. N. Charushin // Journal of Organometallic Chemistry. - 2005. - Vol. 690, № 11. - P2783-2786

Аннотация: Acidic hydrolysis of N-acyl 1-methyl- and 1-phenyl-3-amino-1,2-dicarba-closo-dodecaboranes has been studied. It has been shown that acidic hydrolysis of diastereomeric amides of 1-methyl-3-amino-1,2-dicarba-closo-dodecaborane results in the partial racemization of the target 3-amino-1-methylcarborane. Under the similar conditions, the hydrolysis of N-acyl-3-amino-1-phenyl-1,2-dicarba-closo-dodecaboranes resulted in amide bond cleavage accompanied by simultaneous deboronation with the removal of boron atom at position 6 of carborane cage and formation of 7,8-dicarba-nido-undecaborane derivative according to 11B and 1H NMR spectroscopy.

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.

Аннотация: A consecutive aromatic nucleophilic substitutions of hydrogen in 1,2,4-triazine 4-oxides and an aza Diels?Alder reaction is a versatile route to carborane-functionalized bi- and terpyridines and their 1,2,4-triazine analogues. The heterocycles facilitate deboronation of the substituted carboranes, and the carborane moiety has a significant influence on the coordination properties of the ligands as well

CYCLOMETALATED IRIDIUM COMPLEXES -- NEUTRON-CAPTURE THERAPY -- PHARMACOPHORES
Аннотация: For the first time, the direct C(sp(2))-H functionalization methodology has successfully been applied to cause nucleophilic modification of mono- and diazine-N-oxides with the 1,2-closo-carborane moiety. As a result of these cross-coupling reactions uncatalyzed by transition metals, a series of novel C-modified heterocyclic and open-chain (vinyl acetylene) carboranes have been obtained. Complexes of phenanthrolinyl-substituted omicron-carborane with Cu(II) of various architectures have been synthesized.

Аннотация: Liposomes encapsulated with lipophilic derivative of 1,2-dicarba-closo-dodecaborane have been obtained and tested for toxicity to glioblastoma U87 cells and biodistribution on a U87MG xenograft mouse model. The liposomes are able to penetrate the tumor and provide boron concentration up to 1.5 mmmmg g–1 with tumor-to-muscle ratio up to 2.4.
