Catalytic CH Bond Activation at Nanoscale Lewis Acidic Aluminium Fluorides: H/D Exchange Reactions at Aromatic and Aliphatic Hydrocarbons

Nanoscopic amorphous Lewis acidic aluminium fluorides, such as aluminium chlorofluoride (ACF) and high-surface aluminium fluoride (HS-AlF(3)), are capable of activating C-H bonds of aliphatic hydrocarbons. H/D exchange reactions are catalysed under mild conditions (40 °C).

Preparation, crystallographic characterization and theoretical study of two isomers of C70(CF3)12

Two isomers of C70(CF3)12 have been isolated from a mixture obtained by trifluoromethylation of C70 with CF3I; their molecular structures determined by X-ray crystallography are in good agreement with the results of theoretical DFT calculations for the most stable C70(CF3)12 isomers.

Sol–gel synthesis of metal fluoride supported Pd catalysts for Suzuki coupling

Highly dispersed Pd nanoparticles on CaF2 prepared by novel non-aqueous sol–gel synthesis have been evaluated as an efficient catalyst system for Suzuki cross coupling.

Tungsten(VI) and tungsten(V) fluoride complexes.

WF(6) reacts with phosphines R(3)P forming 1:1 compounds. With R=P(CH(3))(3) the coordination around the tungsten atom is capped trigonal prismatic, with R=P(CH(3))(2)C(6)H(5) the coordination is capped octahedral, as established by single-crystal structure determinations: [(CH(3))(3)P--WF(6)]: a=752.5(21), b=945.7(24), c=629.8(18) pm. beta=110.36(13) degrees , space group Cm, Z=2; [(CH(3))(2)(C(6)H(5))P--WF(6)]: a=762.2(2), b=1123.5(2), c=2647.5(6) pm, space group Pbca, Z=8. [(CF(3)CH(2))(2)N--WF(5)] reacts smoothly with P(C(6)H(5))(3) forming known P(C(6)H(5))(3)(F)(2) and [(CF(3)CH(2))(2)N--WF(4)--P(C(6)H(5))(3)], a stable, green, molecular species, identified among other methods with an crystal structure determination: a=914.9(1), b=956.0(1), c=1449.8(2) pm, alpha=7.642(4), beta=81.648(3), gamma=81.519 degrees , space group P
