arylation of pyridylsulfides with good functional group tolerance was developed. To demonstrate synthetic utility, the resulting pyridylsulfonium salts were used in a scalable transition-metal-free coupling protocol, yielding functionalizedbipyridines with extensive functional group tolerance. This modular methodology permits selective introduction of functional groups from commercially available pyridyl
Bulky diadamantyl aryl phoshine ligands were synthesized and utilized in Buchwald‐Hartwig couplingreactions of sterically demanding ortho‐substituted arylchlorides. The ligands also showed enhanced catalytic activity in the coupling of tosyl hydrazones and aryl halides.

A general route to ruthenium pyridocarbazole half-sandwich complexes is presented and applied to the synthesis of sixteen new compounds, many of which have modulated protein kinase inhibition properties. For example, the incorporation of a fluorine into the pyridine moiety increases the binding affinity for glycogen synthase kinase 3 by almost one order of magnitude. These data are supplemented with cyclic voltammetry experiments and a protein co-crystallographic study.

Pyrrolopyridine compounds of formula (I) or their pharmaceutically acceptable salts are disclosed, which may be suitable for imaging tau aggregates, b-sheet aggregates, beta-amyloid aggregates or alpha- synuclein aggregates, and hence are useful in binding and imaging tau aggregates in Alzheimer's patients. More specifically, the compounds are used as tracers in positron emission tomography (PET) imaging to study tau deposits in brain in vivo to allow diagnosis of Alzheimer's disease and other neurodegenerative diseases characterized by tau pathology. Futher, the compounds are useful for measuring clinical efficacy of therapeutic agents for Alzheimer's disease and other neurodegenerative diseases characterized by tau pathology.

Palladium‐catalyzed couplingbetweenarylhalides, especially less reactive ones or N‐heteroaryls, and trimethylsilylacetylene in the presence of dimethylaminotrimethyltin generated the coupled products in high yields. The reaction does not need CuI and base as auxiliary agents.
