New copper(II) ternary complexes formulated as [Cu(N-N)BIG]ClO4, where BIG is deprotonated 2-((1H-benzimidazol-2-yl)methylamino)acetic acid and N-N represents 2,2?-bipyridine (1) or 4,4?-dimethyl-2,2?-bipyridine (2) or 5,5?-dimethyl-2,2?-bipyridine (3) or 1,10-phenanthroline (4) or 4,5-diazafluoren-9-one (5) or dipyridylamine (6), were synthesized and characterized using analytical and spectral methods. Complex 1 was characterized using single-crystal X-ray diffraction analysis and found to be monomeric in nature with distorted square pyramidal geometry. The binding interactions of 1?6 with calf thymus DNA were studied using UV?visible absorption and emission spectroscopy and viscosity measurements. The DNA cleavage ability of 1?6 with pUC19 DNA shows that the complexes can cleave DNA without any external agents. The ligand and complexes were investigated for their in vitro antibacterial activity against Bacillus subtilis and Staphylococcus aureus. The complexes showed enhanced antibacterial activities compared to the free ligand. Molecular docking studies of complexes 1?6 were made using Genetic Optimization of Ligand Docking (GOLD) software. The study indicated that LEU23, ASP25, ILE84, ASN144 and ARG87 of COX-2 were important for strong hydrogen bonding interaction with the complexes. Among the complexes, 2 showed the best docking result with COX-2. Cytotoxicity assay was performed using MTT reagent against human cervical cancer cells, human breast cancer cells and human lung cancer cells. The complexes were found to show moderate anticancer activity.

Deoxyfluorination of alcohols was carried out using N,N-diethyl-alpha, alpha-difluoro-(m-methylbenzyl)amine (DFMBA). Primary alcohols were effectively converted to fluorides under microwave irradiation or conventional heating. Deoxyfluorination of an anomeric hydroxy group in sugars by DFMBA proceeded at below room temperature and glycosyl fluorides could be obtained in good yields. The deoxyfluorination reaction chemoselectively proceeded and various protecting groups on the sugar can survive under the reaction conditions.

Suzuki cross-coupling reactions of an unprecedented array of unactivated primary and secondary alkyl halides (including challenging alkyl chlorides) can be accomplished through the use of nickel/amino alcohol-based catalysts. Both the nickel precatalyst and the amino alcohols (prolinol or trans-2-aminocyclohexanol) are commercially available and air-stable. In view of the remarkable diversity of amino alcohols that are readily accessible, this discovery may open the door to the rapid development of versatile catalysts for a wide range of cross-coupling processes.

Two dinuclear Cu(II) complexes of formula [Cu2(dpyam)2(mu-C2O4) (Cl)2] (1) and [Cu2(dpyam)2(mu-C2O4) (CF3SO3)2]n (2) (dpyam = di-2-pyridylamine) have been synthesized and their spectroscopic and magnetic properties characterized. The structure of 1 is made up of the centrosymmetric dinuclear [{Cu(dpyam)(Cl)}2(mu-C2O4)] units, while 2 contains chains of the dimeric [Cu2(dpyam)2(mu-C2O4) (CF3SO3)2] units linked by the triflate anions. The two copper atoms in both compounds are linked through a bis-didentate oxalato group leading to a metal-metal separation of 5.526(1) and 5.228(3) A?. The stereochemistry of the Cu(II) chromophore in 1 is approximately square pyramidal, while compound 2 displays an elongated octahedral Cu(II) environment. The IR, ligand field and EPR measurements are in agreement with the structures found. The magnetic susceptibility measurements, measured from 5 to 350 K, revealed a very strong antiferromagnetic interaction between the Cu(II) atoms with a singlet-triplet energy gap (J) of -274 and -342 cm-1, for compounds 1 and2, respectively, in agreement with the coplanarity of the magnetic orbitals.

Crystallographic details for complexes [Cu(I)dipyam(CO)Cl] (1) and [Cu(II)dipyam(CH3CO2)Cl] (2) are as follows: complex 1, triclinic, space group P1- with a = 9.944(3), b = 9.450(3), c = 7.053(3)A, alpha = 69.50(2), beta = 91.81(2), gamma= 76.33(2)°, Z = 2; complex 2, triclinic, space group P1- with a = 10.093(3), b = 9.098(3), c = 7.444(2)A, alpha = 106.24(2), .bet a. = 96.91(2), gamma = 78.87(2)°, Z = 2. The dry carbonyl complexes are thermostable at 100°C or more, but their formation was reversible in solution even at room temperature. Thermal and chemical stabilities increase from the chloro to the iodo species. Among the acetatoderivatives the chloro and bromo mono-dipyam complexes were easily form ed, while the iodide gave preferentially the bis-dipyam complex. Each series of the complexes gave very similar IR spectra in the range 3800-250cm**-1.

The magnetostructural properties of 1-8 have been probed in detail by variable temperature magnetic measurements and crystallographic methods. 1-6 display mononuclear structures while 7 and 8 form 1-D chain structures. Complexes 4-6 have the potential to form 1D-chains via L2 bridging, but instead form mononuclear complexes. Magnetic studies show that complexes 1, 2, and 4 remain in the high-spin (HS) state at all temperatures. An aged, dry, powdered sample of 3 gives an abrupt HS to LS transition (T1/2 = 200 K), while a freshly prepared, powdered sample of 3·1.5H2O displays thermal hysteresis (Delta = 7 K). Complexes 5, 6 and 7 undergo a gradual spin transition with T1/2 values of 100 K, 150 K and 130 K, respectively. Cooperativity parameters are compared, with 3 showing cooperativity (positive C) and 5 and 6 showing anticooperativity. Photomagnetic LIESST (light induced excited spin state trapping) studies were performed on complexes 5 and 6 and reveal T(LIESST) values lower than 60 K. An attempt has been made to understand the electronic structure of complex 3 and its cooperativity behaviour using density functional methods, the calculations reproducing the sign and, in part, the magnitude of the cooperativity.
