Reaction of a ‘VCl2·nTHF’ solution, prepared by the reduction of VCl3(THF)3 with NaBEt3H in THF, and Lidpa (dpa= the anion of 2,2%-dipyridylamine) in a mixture of THF/toluene at reflux temperature yields the bioctahedral V2(dpa)4·THF (1) compound. A similar reaction performed in THF at 0°C gave [V2(dpa)3(m-Cl)2Li2(THF)6][BEt3H] (2), in which a dpa ligand adopts a novel ‘doubly-chelating/bridgin...
restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (bha) and butylated hydroxytoluene (bht) are being imposed because of their carcinogecity. in this investigation optimization of phenolic extraction process frome methanolic (80%) extract (v/v) of elaegnus angustifolia through response surface methodology by fulin cio- calteu is performrd for op...
Reactions of scandium terminal imido complexes with CuI and [M(COD)Cl](2) (M = Rh, Ir) show two interesting reaction patterns, and the formed heterobimetallic complexes have intriguing structural features and show promising catalytic properties.
Three different kinds of cyclic imides with imido protons are chosen to interact with Hg(II): succinimide, the simplest cyclic imide (five-membered ring); phthalimide (conjugated five-membered ring); and 1,8-naphthalimide (conjugated six-membered ring). Based on the results of MS, (1)H-NMR, XPS, IR spectroscopy and fluorescence response analyses, it is suggested that N-unsubstituted cyclic imid...
