Metal-catalyzed activations of inert sp3C–H bonds have recently brought a revolution in the synthesis useful molecules and molecular materials, due to interest formed sp3C–SiR3 silanes, stable organometallic species, for further functionalizations that cannot reach directly.

Palladium-catalyzed Hiyama cross-coupling reactions of various arylsulfonyl hydrazides with a wide variety of aryl silanes have been achieved in good to excellent yields under simple conditions. The newly developed catalytic system does not require the use of expensive silver- or copper-based stoichiometric oxidants and can be accelerated by the addition of TBAT under an atmosphere of oxygen. T...

The formation and structure of alkyltrichlorosilanes on several types of SrTiOs substrates have been studied. The silanes adsorb spontaneously from a hexadecane solution and form monolayers on all the substrates used. Characterization has been performed by atomic force microscopy, wettability, angle resolved X-ray photoelectron spectroscopy, reflection absorption infrared spectroscopy, and spec...

We briefly survey the economics literatures that relate to law and entrepreneurship, including the "law and finance" literature launched by the work of Rafael La Porta, Florencio Lopez-de-Silanes, Andrei Shleifer, and Robert Vishny ("LLSV"). Relying on the suggestive work of LLSV and other economists who have labored over the connections between entrepreneurship and law, we suspect that courts ...
