The present invention describes chemical systems and methods for silylating aromatic organic substrates, said system comprising a mixture of (a) at least one organosilane and (b) at least one strong base, said system being substantially free of a transition-metal compound, and said methods comprising contacting a quantity of the organic substrate with a mixture of (a) at least one organosilane and (b) at least one strong base, under conditions sufficient to silylate the aromatic substrate; wherein said system is substantially free of a transition-metal compound.
Trisubstituted bicyclic heterocyclic compounds (e.g., chromenones and quinolines) and pharmaceutical compositions that modulate kinase activity, including PI3 kinase activity, and methods of treatment of diseases and conditions associated with kinase activity, including PI3 kinase activity, are described herein.
Provided is an organic electroluminescence device having high luminous efficiency, high heat resistance and an extremely long lifetime. The organic electroluminescence device of the present invention includes an organic thin film layer composed of one or more layers containing at least a light emitting layer is interposed between a cathode and an anode. The light emitting layer includes a compound containing a condensed ring and a luminescent metal complex capable of emitting light having a red-based color. It is preferable that the compound containing a condensed ring includes a host material, while the luminescent metal complex capable of emitting light having a red-based color includes a phosphorescent dopant.
