Regiodivergent Cross-Dehydrogenative Coupling of Pyridines and Benzoxazoles: Discovery of Organic Halides as Regio-Switching Oxidants
Cross-dehydrogenative coupling (CDC) of two unfunctionalized heteroarenes has been recognized as an ideal transformation to synthesize privileged heterobiaryl scaffolds. However, regioselective activation and transformation of a specific set of two heterocyclic C-H bonds among other bonds have been extremely challenging. Thus, discovering a new controlling element to achieve regio-controlled and regio-divergent heterocyclic CDCs is considered crucial. In this Letter, the unprecedented use of organic halides as an oxidant to achieve the CDC reaction of pyridines and benzoxazoles with palladium catalyst is described. Moreover, the regioselectivity of the pyridine functionalization site can be controlled by the choice of organic halides.

Palladium-catalyzed synthesis of benzoxazoles by the cleavage reaction of carbon-carbon triple bonds with o-aminophenol
A novel and mild procedure for efficient synthesis of benzoxazoles by the cleavage reaction of carbon-carbon triple bonds with o-aminophenol in the presence of a catalytic amount of palladium chloride has been successfully developed, which provides rapid and efficient access to benzoxazoles. the Partner Organisations 2014.

Flash Vacuum Pyrolysis of Aromatic Oximes
Flash vacuum pyrolisis (FVP) of benzaldoximes and aryl ketoximes afforded nitriles and additional aromatic compounds which were presumably generated from intermediary iminyl radicals.The FVP also gave benzoxazoles, which were presumably formed from iminoxyl radicals.Benzyl ketoximes afforded indoles together with fragmentation products of the iminyl radicals.Keyword---gas-phase pyrolysis; flash vacuum pyrolysis; FVP; flash thermolysis; oxime; iminyl radical; iminoxyl radical; substituted indole; benzoxazole; mass spectra
