Abstract:
A method for the preparation of allylsilanes. The method comprises contacting magnesium metal with a mixture comprising diethylene glycol dibutyl ether, allyl halide, and a halosilane at a temperature within a range of about 5.degree. C. to 20.degree. C. The method provides a high yield of allylsilane product that is easily recoverable and also provides for high ratios of allylsilane to hexadiene by-product.
Abstract:
A process for reacting organic halides with disilanes to form monosilanes. The process uses disubstituted palladium compounds as catalysts. The process is especially useful for reacting alkenyl chlorides, such as allyl chloride, with disilanes to form monosilanes having alkenyl substitution. The process is also useful for converting the high-boiling disilane containing fraction resulting from the direct process for forming organosilanes into more useful monosilanes.
Abstract:
A one-step process for preparation of organosilanes. The process comprises contacting magnesium metal with a mixture comprising an organic halide and a halosilane in a co-solvent comprising about one to 15 moles of a dialkyl ether comprising less than seven carbon atoms, per mole of the allyl chloride; and about 0.05 to less than two moles of a liquid aromatic hydrocarbon solvent per mole of the dialkyl ether; at a temperature within a range of about 5.degree. C. to 200.degree. C.
Abstract:
A process for making .beta.-alkenyltrimethylsilanes and trimethylsilyl carboxylates. The process comprises contacting a mixture comprising hexamethyldisilane and an alkene carboxylate having a .beta.-unsaturated carbon atom with novel organo-palladium and organo-nickel complexes, as catalysts, at a temperature within a range of about 100.degree. C. to 250.degree. C. The present process is especially useful for making allyltrimethylsilane and trimethylsilyl acetate.
Abstract:
A one-step process for the preparation of organodisilanes. The process comprises contacting magnesium metal with a mixture comprising diethylene glycol dibutyl ether, an organic halide, and a halodisilane at a temperature within a range of about 0.degree. C. to 250.degree. C. The process provides a high yield of organodisilane product that is easily recoverable. The present process is especially useful for converting halodisilanes in a high-boiling mixture resulting from the direct process for making organosilane monomers into hexaorganodisilanes.
Abstract:
A process for reacting organodisilanes with organic halides to form monosilanes. The process comprises heating a mixture comprising an organodisilane and an organic halide at a temperature within a range of about 100.degree. C. to 350.degree. C. The process is especially useful for reacting alkenyl chlorides, such as allyl chloride, with organodisilanes to form organomonosilanes having alkenyl substitution. The process is also useful for converting a high-boiling organodisilane containing fraction from a direct process for forming organosilanes into more useful monosilanes.
Abstract:
A system, apparatus, and method for electronically transferring funds using a multi-functional peripheral device. The multi-functional peripheral device may include a housing, a bezel coupled to an exterior of the housing, and at least one sensor device coupled to the bezel. The at least one sensor device can be configured to detect at least one sensory input.
Abstract:
In one embodiment, a system and method to transfer money may include a mobile device associated with a player, a location server designed to: track a device position of the mobile device and track a vessel position, and a mobile gaming management server designed to: receive a fund transfer request from a gaming server for the mobile device, the fund transfer request including a fund amount; determine if the fund amount can be transferred to the mobile device based on the device position and the vessel position; and transfer the fund amount to the mobile device if it is determined that the fund amount can be transferred to the mobile device.
