An unprecedented rhodium-catalyzed selective cleavage of double alkyl-oxygen bonds of bis/tris(o-alkyloxyphenyl)phosphine has been realized, in which P atom functions as a directing group and simple aryl acids are the methyl group acceptor to provide methyl esters and a quaternary phosphonium salt. The preliminary mechanism was investigated via an 18O labeling experiment and stoichiometric reaction between a Rh-A crystal and an aromatic acid.

Diphenylethenyl- and methylphenylethenyl-substituted triphenylamines were prepared by condensation of trimethoxy-substituted triphenylamines with 2,2-diphenylacetaldehyde or 2-phenylpropionaldehyde respectively. The synthesized compounds were found to be

A simple and efficient methodology for the synthesis of triphenylamines has been demonstrated using copper catalyst with a ligand and tripotassium phosphate as the base. The effect of parameters such as catalyst precursors, ligands, bases and solvents were studied and a series of triphenylamines were obtained with moderate to excellent yields in DMF. This reaction displays great functional groups compatibility in the presence of a broad range of functional groups.

A two-electron oxidation of N,N,N′,N′-tetrakis(2-methoxyphenyl)-1,3-diaminobenzene 12 gives the diradical dication 122{radical dot}+, which is an aza analogue of the Schlenk hydrocarbon and, like the Schlenk hydrocarbon, has a triplet ground st
The synthesis of bromo and iodo trifunctionalised tribenzosilatranes

A reliable synthetic route towards selective derivatisation at the 6′,6″ and 6? positions of tribenzosilatranes with bromo or iodo groups has been developed. As these groups can be reacted further, this extends the chemistry associated with tribenzosilatranes. In this report we present a direct synthesis of bromo 8 and iodo 9 trisubstituted tribenzosilatranes. Commercially available o-anisidine 1 was transformed into the triarylamine 3 in a two-step sequence, which was halogenated to furnish the tribromo 4 or the triiodo 5 substituted triamines, respectively. Subsequent deprotection of the methyl ethers furnished the novel tripod ligands 6 and 7. A transilylation reaction in the last step led to the synthesis of the desired para-halogenated tribenzosilatranes 8 and 9.
p-Doped high spin polymers

, p. 2343 - 2354 (2007/10/03)
High spin polymers have been created from p-doping of networked polyaryl and polyarylamine polymers which were synthesized using the Pd0 mediated coupling reaction of aryl di- and tri-bromides with aryl bis- and tris-boronic acids. The doping p
