We report the synthesis and characterization of novel bistetracenes, an unconventional, linearly extended conjugated core with eight fused rings. Also described are bisoligoacenes. In general, the properties and stability of large polycyclic aromatic hydrocarbons (PAHs) strongly depend on the mode of ring annellation and the topology of their it-electron systems, which are usually associated with the resonance stabilization energy in large PAHs.

The present invention is directed to a mild, efficient, and general direct C(sp)-H bond silylation. Various embodiments includes methods, each method comprising or consisting essentially of contacting at least one organic substrate comprising a terminal alkynyl CH bond, with a mixture of at least one organosilane and an alkali metal hydroxide, under conditions sufficient to form a silylated terminal alkynyl moiety. The methods are operable in the substantially absence of transition-metal compounds. The systems associated with these methods are also disclosed.

The present invention describes chemical systems and methods for silylating heteroaromatic organic substrates, said system consisting essentially of a mixture of (a) at least one organodisilane and (b) at least alkoxide base, preferably a potassium alkoxide base, and said methods comprising contacting a quantity of the organic substrate with a mixture consisting essentially of (a) at least one organodisilane and (b) at least one alkoxide base, preferably a potassium alkoxide, under conditions sufficient to silylate the heteroaromatic substrate.

Methods for preparing a catalyst precursor material from dihalo-substituted metalloids are provided. The methods In include mixing a first solution of a halogenated alkane, at least one solvent, and a first component selected from a dihalo-substituted-group-14 metalloid or an organolithium reagent in a first reaction zone. Continuously adding the first solution to a second reaction zone, and continuously adding a second solution to the second reaction zone. The second solution including at least one solvent and a second component of either the dihalo-substituted-group-14 metalloid or the organolithium reagent, the second component is different from the first component. Mixing the first solution and the second solution in the second reaction zone.
