Calcium Hydride Catalysts for Olefin Hydrofunctionalization: Ring-Size Effect of Macrocyclic Ligands on Activity

The fifteen-membered NNNNN macrocycle Me5PACP (Me5PACP=1,4,7,10,13-pentamethyl-1,4,7,10,13-pentaazacyclopentadecane) stabilized the [CaH]+ fragment as a dimer with a distorted pentagonal bipyramidal coordination geometry at calcium. The hydride complex was prepared by protonolysis of calcium dibenzyl with the conjugate acid of Me5PACP followed by hydrogenolysis or treating with nOctSiH3 of the intermediate calcium benzyl cation. The calcium hydride catalyzed the hydrogenation and hydrosilylation of unactivated olefins faster than the analogous calcium complex stabilized by the twelve-membered NNNN macrocycle Me4TACD (Me4TACD=1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclododecane). Kinetic investigations indicate that higher catalytic efficiency for the Me5PACP stabilized calcium hydride is due to easier dissociation of the dimer in solution when compared to the Me4TACD analogue.

Strontium Hydride Cations Supported by a Large NNNNN Type Macrocycle: Synthesis, Structure, and Hydrofunctionalization Catalysis

The use of the 15-membered NNNNN macrocyclic ligand Me5PACP (Me5PACP = 1,4,7,10,13-pentamethyl-1,4,7,10,13-pentaazacyclopentadecane) allowed the isolation of two cationic strontium hydride complexes by hydrogenolysis of benzyl precursors. Treatment of sparingly soluble [(Me5PACP)Sr(CH2Ph)2] with dihydrogen gave free Me5PACP, toluene, and oligomeric strontium hydride [SrH2]n, while hydrogenolysis in the presence of 1 equiv of the benzyl cation [(Me5PACP)Sr(CH2Ph)][B(C6H3-3,5-Me2)4] enabled isolation of the thermally unstable trihydride cation [(Me5PACP)2Sr2(μ-H)3][B(C6H3-3,5-Me2)4]. When the benzyl cation [(Me5PACP)Sr(CH2Ph)][BAr4]2 (Ar = C6H3-3,5-Me2 or C6H4-4-nBu) was reacted with dihydrogen or n-octylsilane, dihydride complexes [(Me5PACP)2Sr2(μ-H)2][BAr4]2 containing a dinuclear core bridged by two hydride ligands were obtained. The soluble dihydride complex [(Me5PACP)2Sr2(μ-H)2][B(C6H4-4-nBu)4]2 was tested in olefin hydrogenation and hydrosilylation catalysis. Kinetic analyses for [(Me5PACP)2Sr2(μ-H)2]2+ showed lower catalytic activity as compared to that of the isostructural calcium homologue [(Me5PACP)2Ca2(μ-H)2]2+. This is explained by a shift in the monomer-dimer equilibrium which precedes the catalytic cycle.

Alkoxy Hydrosilanes As Surrogates of Gaseous Silanes for Hydrosilylation of Alkenes

Me2SiH2, MeSiH3, and SiH4 are gaseous and flammable silanes that are inconvenient to use in chemical reactions. Catalytic amounts of a nickel pincer complex and NaOtBu are reported to allow the synthesis of alkyl hydrosilanes from alkenes and alkoxy hydrosilanes, leading to the replacement of Me2SiH2, MeSiH3, and SiH4 by Me2(MeO)SiH, Me(EtO)2SiH, and (MeO)3SiH in hydrosilylation reactions of alkenes. The scope and mechanism of the reactions are also described.

Trialkylsilylethynyl-substituted triphenylenes and hexabenzocoronenes: Highly soluble liquid crystalline materials and their hole transport abilities

Four triphenylene (TP) and four hexa-peri-hexabenzocoronene (HBC) derivatives with trialkylsilylethynyl groups were prepared and characterized by differential scanning calorimetry, polarizing optical microscopy, and X-ray diffraction measurements. All compounds were highly soluble in less-polar organic solvents and exhibited a columnar phase, Colh or Colr for the TPs, and Colh for the HBCs. The hole transport ability in the HBCs' columnar phase, 0.4-1.5×10-3 cm2 V-1 s-1 at 40-180°C, and its temperature dependence were determined by the time-of-flight method using a solution technique.
