Lewis-base adducts of lead(II) compounds. XV synthesis and structure of some adducts of Bis(2-pyridyl)amine with lead(II) salts

Several complexes of bis(2-pyridyl)amine (‘dpa’) with lead(II) salts have been synthesized and subjected to room-temperature single-crystal X-ray studies. 1:1 Adducts have been obtained with lead(II) bromide and iodide. They have similar unit cells, also similar to those of a variety of other N,N?-heteroaromatic bidentate ligand adducts with metal(II) halides, and the C2/c cell described elsewhere in this series may be regarded as archetypical. [(dpa)PbBr2](?/?) is monoclinic, P 21/a, a 9.791(4), b 9.720(4), c 16.498(4) A, beta 95.96(4), Z = 4 f.u.; conventional R on |F| at convergence was 0.066 for N = 2717 ‘observed’ (I > 3sigma(I)) reflections. [(dpa)PbI2](?/?) is monoclinic. P21/c, a 8.299(2), b 10.229(3), c 16-905(5) A, beta 101.47(2), Z = 4 f.u.; R was 0.044 for N 2140. Both complexes, like their 2,2?-bipyridine and 1,10-phenanthroline analogues, are linear polymers with six-coordinate (cis-N2)Pb(mu-X)4 environments linked in infinite … (mu-X)2Pb(mu-X)2…one-dimensional chains, and with dpa being bidentate. A 2:1 adduct of bis(2-pyridyl)amine with lead(II) acetate (‘Pb(ac)2?) is also described. [(dpa)2Pb(ac)2](?/?) is monoclinic, C 2/c, a 28.835(5), b 10.868(3), c 7.665(2) A, beta 94.21(2), Z = 4; R was 0.029 for N 1854. The complex is a linear polymer along c; the lead atom lies on a crystallographic twofold axis with a coordination environment comprising a pair of symmetry-related dpa ligands, in this case unidentate (Pb-N 3.092(6) A), and a pair of symmetry-related bidentate acetate ligands (Pb-O 2.465(4) and 2.568(5) A) with the first oxygen atom performing an additional bridging function to adjacent symmetry-related lead atoms (Pb-O 2.663(4) A).

Cationic dipyridylamine substituted zinc tetrapyrazinoporphyrazine derivatives for photodynamic therapy

Two kinds of cationic zinc tetrapyrazinoporphyrazine derivatives substituted with ortho- or para- methylpyridinium groups on the peripheral position were synthesized and characterized. The solubility and aggregation behavior of each material were estimated in various solvents, which show different aspect depending on the position of nitrogen on methylpyridinium groups. The fluorescence quantum yield (PhiF) values of both cationic tetrapyrazinoporphyrazines were measured and the singlet oxygen quantum (PhiDelta) yield value were measured by indirect method with DPBF (1,3-diphenylisobenzofuran) in DMSO. Both PhiF and PhiDelta of cationic zinc tetrapyrazinoporphyrazine derivatives exhibited reasonable values for photodynamic therapy application. The cationic zinc tetrapyrazinoporphyrazine derivatives substituted methylpyridinium groups increased solubility in aqueous solvent but also showed the suitable properties as the photosensitizers for photodynamic therapy.

Enantioselective Synthesis of alpha-Amidoboronates Catalyzed by Planar-Chiral NHC-Cu(I) Complexes

The first highly selective catalytic hydroboration of alkyl-substituted aldimines to provide medicinally relevant alpha-amidoboronates is disclosed. The Cu(I)-catalyzed borylation proceeds with excellent facial selectivity when a set of planar-chiral N-heterocyclic carbenes (NHCs) were employed as ligands. Density functional theory computations suggest that interactions between BPin and the planar-chiral catalyst are responsible for the observed stereoselectivity. Important pharmacophores, such as the boronate analogue of isoleucine, can be prepared using a chromatography-free protocol starting from commercially available reagents. The application of these NHC ligands in these Cu(I)-catalyzed processes offers a significant contribution to existing strategies for laboratory-scale preparation of enantioenriched alpha-amidoboronates.
