Визначено проблеми української економіки, що зумовлені зокрема недосконалістю розвитку та підтримки соціальної складової. Зазначено переваги від формування стратегії соціально-економічного розвитку держави на регіональному рівні. Запропоновано актуальні напрями реалізації регіональних проектів у соціальній сфері.В статье проанализированы основные факторы, которые обусловливают необходимость решения современных проблем в сфере социально-экономического развития отечественных регионов. Детально прокомментированы основные показатели социально-экономического развития в Украине. Определены проблемы украинской экономики, которые обусловлены в частности несовершенством развития и поддержки социальной составляющей. Определены преимущества от формирования стратегии социально-экономического развития государства на региональном уровне. Предложены актуальные направления реализации региональных проектов в социальной сфере.The article analyzes the main factors that contribute to the need to solute urgent issues in the sphere of social and economic development of regions. It is commented in detail the main indicators of social and economic development in Ukraine. The problems of the Ukrainian economy caused by imperfections including development and maintenance of the social component are identified. The benefits from the formation of social and economic development at the regional level are indicated. Directions of regional projects realization in the social sphere are proposed.
Modern regional development of Ukraine confirms spread of negative trends such as deepening of regional disparities, worsening of social and economic problems of the regions due to lack of effective system of implementation of the state regional policy in social and economic sphere. It is necessary to regulate regional development of Ukraine with strengthening of effective factors through qualitative use of decentralization of power due to reduced direct financial assistance and the use of preferences and guarantees.
The main areas of regional projects implementation in the social sphere should be: creating long-term plan of infrastructure development in the regions; joint development of communal medical network, wellness and spa and other facilities of social purpose with departmental, business and private funding.
There are such advantages of forming a strategy of social and economic potential of the state at the regional level: the needs of the region is best known for stakeholders (regional governments, businesses, NGOs, local communities); definition of strategic directions of development at the regional level encourages businesses, organizations, non-profit sector, local communities in the process of regional governance; promoting decentralized management processes; the possibility of optimal coordination of local interests with regional and so on
NCN-Type Pincer Complexes of Subporphyrinatoboron(III)
The first NCN-type subporphyrin pincer
complexes <b>3Pd</b> and <b>3Pt</b> have been synthesized
via Suzuki coupling of 2,13-diborylsubporphyrin with 2-iodopyridine,
followed by metalation with PdCl<sub>2</sub>(MeCN)<sub>2</sub> or
K<sub>2</sub>PtCl<sub>4</sub>, respectively. 2,13-Diiminosubporphyrin <b>4</b> was also prepared via formylation of 2,13-dilithiosubporphyrin
followed by imination with aniline but was found to be unsuitable
as a precursor of organometallic species. The complexes <b>3Pd</b> and <b>3Pt</b> displayed perturbed optical
properties presumably due to the d(metal)π(subporphyrin)
orbital interactions
Metal Complexes of <i>meso–meso</i> Linked Corrole Dimers
Cobalt,
gallium, silver, and copper complexes of 5,5′-linked corrole
dimer <b>1</b> and 10,10′-linked corrole dimer <b>2</b> were synthesized by metalations with Co(OAc)<sub>2</sub>·4H<sub>2</sub>O, GaCl<sub>3</sub>, AgOAc, and Cu(OAc)<sub>2</sub>·H<sub>2</sub>O, respectively, in good yields. The structures
of cobalt(III), gallium(III), and silver(III) complexes have been
unambiguously revealed by X-ray diffraction analysis. Their optical
and electrochemical properties have been studied, which revealed different
electronic interactions between the two corrole units depending upon
the positions of <i>meso–meso</i> linkage and axial-ligand
coordination modes

Synthesis of Spirocyclic Diarylfluorenes by One-Pot Twofold S<sub>N</sub>Ar Reactions of Diaryl Sulfones with Diarylmethanes
Treatment
of dibenzothiophene dioxides with cyclic diarylmethanes
in the presence of KN(SiMe<sub>3</sub>)<sub>2</sub> results in the
formation of fluorene-based spirocyclic tetraarylmethanes in a single
operation. The transformation would proceed via an intermolecular
S<sub>N</sub>Ar reaction of the dioxides with cyclic diarylmethylpotassium
followed by intramolecular S<sub>N</sub>Ar cyclization. This straightforward
strategy provides a wide range of spirocyclic diarylfluorenes including
unusual ones that are otherwise difficult to synthesize
Regiocontrolled Palladium-Catalyzed Arylative Cyclizations of Alkynols
Tuning the reactivity
of arylpalladium intermediates enables control
of catalytic arylative <i>5-exo</i> and <i>6-endo</i> cyclizations of alkynols. The two modes of cyclizations represent
a rare example of controllable, regioselective difunctionalization
of alkynes. The cyclizations are useful in offering a divergent synthesis
of oxygen-containing heterocycles, which is of synthetic use for further
derivatization. Formal synthesis of an hNK-1 receptor antagonist also
showcases the utility of our arylative cyclization
Synthesis of 1,2-Disubstituted Cyclopentenes by Palladium-Catalyzed Reaction of Homopropargyl-Substituted Dicarbonyl Compounds with Organic Halides via 5-<i>Endo-Dig</i> Cyclization
Palladium catalysts with bulky biaryl phosphine ligands allow homopropargyl-substituted dicarbonyl compounds to undergo intramolecular addition via a rare 5-<i>endo-dig</i> pathway. C–C bond forming reductive elimination follows the addition to introduce alkenyl and alkynyl as well as aryl groups by using the corresponding organic halides. The cyclization is versatile enough to be applicable to the synthesis of highly substituted dihydropyrrole and a fused tricyclic compound
<i>meso‑β</i> Dibenzo[<i>a,g</i>]corannulene-Fused Porphyrins
FeCl<sub>3</sub>-mediated oxidative
fusion of <i>meso</i>-linked dibenzo[<i>a,g</i>]corannulene–porphyrin
dyads <b>6M</b> afforded fused porphyrins <b>7M</b> bearing
a five-membered ring connection, but similar oxidation of β-linked
dyads <b>9M</b> provided fused porphyrins <b>10M</b> bearing
a six-membered ring connection, both in a regiospecific manner. While
fused dyads <b>10M</b> exhibit modestly red-shifted absorption
and fluorescence profiles, fused dyads <b>7M</b> display characteristically
red-shifted absorption bands reflecting antiaromatic dehydropurpurin
electronic networks
