The title compound, [NiCl(2)(C(3)H(9)P)(3)], was obtained as a product of the reaction of [NiCl(2)(PMe(3))(2)] with an equivalent trimethyl-phosphine in diethyl ether. It easily loses trimethyl-phosphine at room temperature to give NiCl(2)(PMe(3))(2). There are two independent mol-ecules in the asymmetric unit, and their bond lengths and angles are similar. The Ni environment is trigonal bipyra...

In the title complex, [Sn(C(2)H(2)ClO(2))(2)(C(4)H(11)Si)(2)], the Sn(IV) ion is coordinated in a distorted tetra-hedral environment formed by two O atoms from two monodenate chloro-acetato ligands and two C atoms from two trimethyl silyl ligands. Two further weak intra-molecular Sn⋯O contacts [2.744 (2) and 2.655 (2) Å] are formed by the chloro-acetato ligands.

rearrangement of propargyl amine salt, in the presence of a base was studied and it was concluded that this occurs through an allenic intermediate.

Abstract The wettability preference of carbonate reservoirs is neutral-wet or oil-wet as the prevailing hydrocarbon reserves that affects approximately half total production hydrocarbons world. Therefore, due to surface rocks notable fraction oil held inside their pores in comparison with sandstones. Since shifting toward water-wet system great interest, numerous components were used for this p...

The dual need to remove CO2 from our emissions and treat alkaline industrial residues such as ash materials motivate the design of innovative pathways simultaneously capture convert into mineralized carbonates. Direct carbon mineralization is one approach that addresses mineralize emissions. Low solubility in water slow kinetics at ambient temperature have challenged direct residues. To address...

The photo catalytic oxidation of Surfactant Hexadecyltrimethyl-ammonium bromide in aqueous diluted solution has been investigated. Compressed air was used as oxidant and the temperature was maintained at 25-30°C. Effect of UV rays alone and in combination of hydrogen peroxide (H O ) and titanium 2 2 dioxide (TiO ) on Hexadecyltrimethyl-ammonium bromide (C H NBr) was recorded. Finally, from HPLC...

cis-polybutadiene was functionalized using in–situ generated dmd as oxidant and tetra-n-butyl ammonium bromide as phase transfer catalyst (ptc). the epoxidation process was investigated by 1hnmr spectroscopy. 1hnmr spectrum analysis of products confirms the absence of ring opening side products in epoxidation reaction. various factors such as reaction temperature, reaction time and the concentr...
