Generation of Phosphonium Sites on Sulfated Zirconium Oxide: Relationship to Br?nsted Acid Strength of Surface -OH Sites

The reaction of (tBu)2ArP (1a-h), where the para position of the Ar group contains electron-donating or electron-withdrawing groups, with sulfated zirconium oxide partially dehydroxylated at 300 °C (SZO300) forms [(tBu)2ArPH][SZO300] (2a-h). The equilibrium binding constants of 1a-h to SZO300 are related to the pKa of [(tBu)2ArPH]; R3P that form less acidic phosphoniums (high pKa values) bind stronger to SZO300 than R3P that form more acidic phosphoniums (low pKa values). These studies show that Br?nsted acid sites on the surface of SZO300 are not superacidic.

Systematic synthesis and crystal structures of tetraaryltellurium compounds Ar4TeIV

Hypervalent tetraaryltellurium(IV) compounds of the type Ar4TeIV(1: Ar = C6H5; 2: Ar = p-H3CC6H4; 3: Ar = p-t-BuC6H4; 4: Ar = p-F3CC6H4) were prepared via a convenient one-pot reaction between the isolated corresponding ArLi reagent and TeCl4. X-ray crystallographic analyses of 14 revealed distorted pseudo-trigonal-bipyramidal (TBP) structures for Ar4Te and the TBP character was analyzed by the dihedral angle method.

Recyclable polystyrene-supported siloxane-transfer agent for palladium-catalyzed cross-coupling reactions

The rational design, synthesis, and validation of a significantly improved insoluble polymer-supported siloxane-transfer agent has been achieved that permits efficient palladium-catalyzed cross-coupling reactions. The cross-linked polystyrene support facilitates product purification with excellent siloxane recycling. Drawbacks of a previous polymer-supported siloxane-transfer agent, relating to reaction efficiency and polymer stability after repeated cycles, have been addressed.

Synthesis and characterization of Lewis base-free, σ-bonded lithium aryls: A structural model for unsolvated phenyllithium in the solid state

The synthesis and characterization of four Lewis base-free, σ-bonded lithium aryls are reported. This work was undertaken in order to provide a model for the solid-state structure of phenyllithium, which is currently unknown. Nondonor hydrocarbon solubili

Tetraphenylcyclopentadiene and (4-tert-Butylphenyl)tetraphenylcyclopentadiene: Synthesis and Characterization of their Alkali-Metal Salts and Metallocenes of Germanium, Tin, and Lead

Tetraphenylcyclopentadiene (1) and (4-tert-butylphenyl)tetraphenylcyclopentadiene (11), their alkali-metal salts (2-4 and 12, 13, respectively)and their air-stable metallocenes of germanium (5, 15), tin (6, 16) and lead (7, 17) were synthesized and characterized by IR, Raman, 1H-NMR, 13C-NMR, and mass spectta as well as by X-ray powder diagrams.Comparative 13C-NMR studies including tetraphenylcyclopentadienyl bromide (8), (4-tert-butylphenyl)tetraphenylcyclopentadienol (9), and (4-tert-butylphenyl)tetraphenylcyclopentadienyl bromide (10) prove a delocalisation of the negative charge from the C5 ring into the nonparallel phenyl ligands.
