权利人:COMMISSARIAT ENERGIE ATOMIQUE
摘要:A one pot single step process is described for the synthesis of a compound, including a labeled compound, containing a sulfonyl functional group comprising the step of mixing together a silane, an SO 2 source, an electrophilic compound, an activating compound and optionally a metal catalyst. A process for producing tracers from a labeled sulfonyl containing compound prepared by the described process is also included.

标题:Initiator compositions and methods for their synthesis and use
发明人：CRIVELLO JAMES V
摘要:Cationic polymerization initiators of formula ##STR1## are disclosed. The acyl sulfonium salts of the present invention differ from known acyl sulfonium initiators in that the substituents R 2 and R 3 on the sulfur are larger and more complex than the lower alkyl and lower alkylene of known photoinitiators. Processes for the synthesis of the novel acyl sulfonium salts and prepolymer compositions containing them are also disclosed.

摘要:The present invention provides a method of making a methylene malonate monomer that includes the steps of reacting a malonic acid ester with a source of formaldehyde optionally in the presence of an acidic or basic catalyst and optionally in the presence of an acidic or non-acidic solvent to form reaction complex. The reaction is optionally performed in the presence of or contacted with an energy transfer means such as a heat transfer agent, a heat transfer surface, a source of radiation or a laser such that reaction complex is substantially vaporized to produce a vapor phase comprising methylene malonate monomer which may be isolated. The present invention further provides methylene malonate monomers prepared by the method of the invention, as well as compositions and products formed from the methylene malonate monomers, including monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).

标题 :Synthesis of tetraalkylsilanes
发明人：EISENBERG DAVID C; ROBINSON GENE C
权利人:ETHYL CORP
摘要:This invention relates to a process for preparing tetrahydrocarbylsilane in high yield, comprising: a) forming a reaction mass from molten metal and trihydrocarbylaluminum, in an hydrocarbon solvent under an inert gas atmosphere; b) maintaining the reaction mass at a temperature in the range of from about 100° to about 130° C. for a period of time sufficient to form sodium tetrahydrocarbylaluminate; c) contacting the sodium tetrahydrocarbylaluminate with organotrihalosilane; and d) heating the contacted tetrahydrocarbylaluminate and organotrihalosilane to a temperature and for a period of time sufficient to form the tetrahydrocarbylsilane, wherein the tetrahydrocarbylaluminate and tetrahydrocarbylsilane are formed at a pressure of less than about 3000 KPa and wherein the hydrocarbyl group of the tetrahydrocarbyl silane is one or a mixture of hydrocarbyl groups having less than about 8 carbon atoms each.
