METHOD FOR PRODUCING CYCLIC SILANE COMPOUND OR SALT THEREOF, SALT HAVING CYCLIC SILANE DIANION, AND CYCLIC SILANE DIANION SALT-CONTAINING COMPOSITION

摘要

An object of the present invention is to provide a production method that can efficiently produce a cyclic silane compound or a salt thereof with a high yield and to provide a novel salt having a cyclic silane dianion that is easy to handle and a cyclic silane dianion salt-containing composition. The method for producing a cyclic silane compound or a salt thereof of the present invention includes the step of allowing a halosilane compound to react in the presence of at least one of a phosphonium salt and an ammonium salt, and a compound represented by a specific formula.
