Wei Wei, Bin Yuan, Song Lv, Qifeng Liao, Jieyang Huang
Journal of Materials Science and Chemical Engineering (MSCE) , 2013, DOI: 10.4236/msce.2013.15013
Abstract: ByBimolecular Nucleophilic Substitution, four new types of alkylene triphenyl double quaternary phosphonium salt were synthesized respectively by using triphenylphosphine, 1,3-dibromopropane, 1,6-dibromohexane,1,10-dibromo- decane, 1,12-dibromododecane as raw materials and using DMAC as the solvent, under a certain temperature and reac- tion time. The productivity is 58% - 83%. The molecular structures of the products were characterized by IR, NMR and elemental analysis. The sterilizing effect of 1,6-hexylidene triphenyl double phosphonium bromide(HTDPB) and 1,12- dodecylidene triphenyl double phosphonium bromide(DoTDPB) was evaluated by using extinct dilution method.The experimental result shows that the sterilizing effect of DoTDPB is better than the effect of HTDPB under the same drug concentration and contact time. When the concentration of DoTDPB was 20 mg/L and the contact time was 0.5 h, the sterilizing rate of DoTDPB used to kill saprophytic bacteria (TGB), sulfate-reducing bacteria (SRB) and iron bacteria (IB) was 95.56%, 84% and 99.58% respectively.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810038286
Abstract: In the cation of the title compound, C32H26OP+·CF3O3S , the dihedral angle between the benzene rings of the biphenyl group is 42.37 (8)°. In the crystal, the cations and anions interact through intermolecular C—H...O hydrogen bonds, forming chains parallel to the b axis. These chains are further linked by C—H...π stacking interactions into layers parallel to the bc plane.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808027712
Abstract: The asymmetric unit of the title salt, C28H28O3P+·Cl ·H2O, contains a benzyltriphenylphosphonium cation, a chloride counter-ion, and a water molecule of crystallization. The 3,4,5-trimethoxy substituents of the benzylic functionality are arranged with the 3,5-methyl groups lying approximately in the aromatic ring plane while the 4-methyl group is out of the plane.

Abstract: The title salt, [P(NHCH2C6H5)4]+·Cl , crystallizes with the P atom and Cl anion lying on a twofold rotation axis. The P atom has a slightly distorted tetrahedral geometry with two classes of N—P—N angles [101.15 (10) and 100.55 (11)° and 113.07 (9) and 114.83 (8)°] and the environments of sp2-hybridized N atoms are essentially planar (sum of angles = 359.9 and 360.1°). In the crystal, the phosphonium ion interacts with each neighboring chloride ion via two approximately equal N—H...Cl interactions, forming parallel chains along the c axis.

Journal of the Brazilian Chemical Society , 1998, DOI: 10.1590/S0103-50531998000200011
Abstract: thermodynamic parameters for the reaction of ch2 (singlet and triplet), cf2 and c(oh)2 carbenes with formaldehyde, acetaldehyde and acetone, forming carbonyl ylides, were determined using high level ab initio molecular orbital calculations. singlet methylene forms a stable ylide with the three carbonyl compounds, with a dho of -41.6 kcal/mol, -40.0 kcal/mol (e isomer), -44.5 kcal/mol (z isomer) and -40.8 kcal/mol, respectively. triplet methylene also forms a ylide with formaldehyde with a de of -15.7 kcal/mol, resulting in the triplet ylide being formed reversibly. for the reaction with formaldehyde, the cf2 and c(oh)2 carbenes have a positive dho of 13.0 kcal/mol and 22.0 kcal/mol, and a dgo of 25.3 kcal/mol and 34.0 kcal/mol, respectively. due to its unfavorable free energy of formation, and the potential competition of direct 1,2 cycloaddition of carbene to the c=o group, cf2 and c(oh)2 should not react with carbonyl compounds forming ylides.
