1,4-bis(triphenyl phosphonium)butane peroxodisulfate(BTPPBPDS) were synthesized by treating 1,4-bis(triphenyl phosphonium)butane dibromide and potassium peroxydisulfate in aqueous solution.This was used mild and efficient reagent for oxidation of alkyl benzenes to their corresponding carbonyl compounds in very good to high yields.

The labile sulfur of adrenodoxin was attacked by a nucleophile, triphenyl phosphine. The product was triphenyl phosphine sulfide regardless of the presence of 02. The stoichiometry between labile sulfur which disappeared and triphenyl phosphine sulfide formed was found to be 1: 1. The initial rate of the reaction follows second order kinetics with a rate constant of 2 to 3 X lo3 M-l mind1 at 38...

The title compound, C(26)H(20)N(2), first reported in 1891, was obtained as a by-product in the preparation of benzildianil from benzil and excess aniline. The dihedral angles between the fused benzene ring and the pendant phenyl rings are 17.93 (11), 53.18 (10) and 89.08 (12)°.

Single phase anatase titania powders with size below 20 nm and surface area of 75 m /g were 2 synthesized by a simple precipitation method at pH 5 and dehydration of agglomerates by azeotropic distillation. The powders were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and BET surface area, after calcinations at 550°C for 3 hrs. This nanoparticles was used for...

In this paper, we characterize the rotational dynamics and observe rotor-rotor interactions within a crystalline, three-dimensional array of dipolar molecular rotors. The rotating portion of each rotor molecule consists of a dipolar fluorine-substituted phenyl group. The phenyl rotors are connected by acetylene linkages to bulky triphenyl methyl groups which are held rigid in the crystal lattic...

The title compound, [Cu(NO(3))(C(18)H(15)P)(3)]·CH(3)OH, is a methanol solvate derivative of nitratotris(triphenyl-phos-phine)copper(I). The complex crystallizes with three triphenyl-phosphine ligands coordinated to the copper centre, with an O-H⋯O hydrogen bond observed between the nitrate ligand and the methanol solvent mol-ecule. The coordination around the Cu(I) centre is distorted tetrahed...
