Claim Text:
1. A method for producing a halogenated cyclic silane compound or a salt thereof, which comprises the step of allowing a halosilane compound to react in the presence of both (A) at least one of a phosphonium salt and an ammonium salt, and (B) a compound represented by the following general formula (i): wherein Z 1 represents N, O, P or S; Z 2 represents O, P or S; R and R″ each independently represent an organic group having a carbon number of 1 to 20, which may contain O, P, S or a halogen atom and may have a straight-chain structure, a branched structure, an alicyclic structure or an aromatic ring structure; R′ represents a hydrogen atom, or an organic group having a carbon number of 1 to 6, which may have a straight-chain structure, a branched structure or a ring structure; 1 is 2 when Z 1 is N or P, 1 is 1 when Z 1 is O or S, m is 2 when Z 2 is P, and m is 1 when Z 2 is O or S; n is an integer of 1 to 5; and when R, R′ or R″ is each plurally present, each may be the same or different, and wherein the halogenated cyclic silane compound or the salt thereof has a silicon-halogen bond, and wherein the compound represented by the general formula (i) contains no tertiary polyamine ligand.
