Luminescent carbon-based materials have been prepared by electrostatic self-assembly of negatively-charged luminescent Eu(iii)-complex with imidazolium-functionalized MWCNTs.
Synthesis and Crystal Structure of Tribromomethyltriphenylphosphonium Bromide and Bis(tribromomethyltriphenylphosphonium) Tribromide Bromide
Vogt, H.,Frauendorf, C.,Fischer, A.,Jones, P. G.
, p. 223 - 228 (2007/10/02)
Tribromomethyltriphenylphosphonium bromide 1 has been prepared by the reaction of triphenylphosphine with tetrabromomethane in dichloromethane.Colourless crystals were obtained by recrystallization from the same solvent.The light-sensitive crystals change
Kinetics of the reaction between triphenylphosphine and some haloalkanes

Kinetics of reactions RX + (C6H5)2P -> (C6H5)3PR+X- (R = CCl3, CBr3, CH2Br, C4H9 and X = Br, Cl, I) have been studied at different temperatures and in different dielectric media.The values of second order rate constants of the reactions with tetrahalomethanes are much higher than those with partially halogenated alkanes.This suggests that the reaction may be of charge transfer type with tetrahalomethanes while with other haloalkanes it is simple nucleophilic substitution reaction of SN2 type.
NOVEL REACTIONS OF PHOSPHONIUM YLIDES WITH PERHALOALKANES: FIRST EXAMPLES OF HALOPHILIC ATTACKS BY PHOSPHONIUM YLIDES AND A FACILE ROUTE TO α-HALOALKYLPHOSPHONIUM SALTS
Li, Xing-Ya,Hu, Jin-Shan
, p. 6317 - 6320 (2007/10/02)
Phosphonium ylides Ph3=CHR (R = H, CH3, C2H5, n-C3H7, n-C5H11) react readily with perhalofluoroalkanes to afford regiospecifically α-haloalkylphosphonium salts Ph3P+-CHXR Y- (X = I, Br, Cl) in good yields.These reactions reveal a new type of reactivity phosphonium ylides, i.e., the halophilic attack on C-X bonds, and may be useful for the regiospecific synthesis of substituted haloolefins via Wittig reaction.
Ionic Products in Reaction between Triphenylphosphine and Tetrabromomethane
Jain, D. V. S.,Chopra, Renu
, p. 709 - 711 (2007/10/02)
The reaction between triphenylphosphine and tetrabromomethane has been found to be very fast and leads to the formation of ionic products, thus leading to a new method for their quantitative estimation.Various features of the conductometric titration curv
