A process for producing a cyclic silane compound, in which a chained polysilane is subjected to pyrolysis in the presence of an oxide of a transition metal belonging to Group 8 or Group 11 of the periodic table; and a process for producing a cyclic carbosilane compound, that includes subjecting a chained polysilane to pyrolysis in the presence of a simple substance of a metal selected from the group consisting of transition metal elements and elements belonging to Groups 12 to 15 of the periodic table, or a compound thereof.

Process for production of cyclic silane compound and/or cyclic carbosilane compound

Benzoic acid derivatives useful as intermediates for the preparation of drugs and agricultural chemicals, particularly compounds having herbicidal activity; and easy and economical processes for the preparation of the same. The processes are specifically those represented by reaction formula for the preparation of compounds represented by general formulae (1) and (6).

Benzoic acid derivatives and processes for the preparation thereof

A process for the preparation of (E)-3-(1-propenyl)-2-isoxazoline, characterized by reacting crotonaldehyde with hydroxylamine to form an oxime, and then converting the oxime into a nitrile oxide while reacting the nitrile oxide with ethylene.

Process for the preparation of (e)-3-(1-propenyl)isoxazoline
