    摘要: The present invention relates to method for producing monosilane and tetraalkoxysilane comprising subjecting alkoxysilane represented by formula (1) HnSi(OR) 4-n  (1) wherein R represents alkyl group having 1 to 6 carbon atoms and n represents an integer of from 1 to 3, to dismutation reaction in a gaseous phase in the presence of a catalyst containing an alkali metal fluoride and a catalyst activator.The method can solve problems in a method for producing monosilane and tetraalkoxysilane by dismutation reaction of alkoxysilane in a liquid phase: i.e. problems such that separation from the solvent is difficult and that the reaction is too slow and not suitable for industrial production.

    摘要: A process for producing a cyanobenzoic acid compound, a cyanobenzamide compound, an alkyl cyanobenzoate compound, and a cyanobenzoyl chloride compound, which are useful intermediates for a variety of chemicals such as pharmaceuticals, agrochemicals, liquid crystals, and monomers for functional polymers. One nitrile group of an easily available phthalonitrile compound is selectively hydrolyzed to thereby produce a cyanobenzamide compound with high selectivity and yield. The cyanobenzamide compound thus-produced is transformed under acidic conditions into a cyanobenzoic acid compound and a cyanobenzoate ester compound without the cyano group of the benzene ring being damaged.
