| Claim: |
1. A process for producing a cyclic silane compound, which comprises subjecting a chained polysilane to pyrolysis in the presence of an oxide of a transition metal belonging to Group 8 or Group 11 of the periodic table. |
| Claim: |
2. The process for producing a cyclic silane compound according to claim 1, wherein the chained polysilane is a compound represented by the following formula (1): [chemical expression included] wherein R1 and R2 each independently represent a C1-C6 alkyl group, an aryl group, or an arylalkyl group; X represents a hydrogen atom, a halogen atom, a hydroxyl group, a C1-C6 alkyl group, a C1-C6 alkoxy group, an aryl group, or a trialkylsiloxy group; m represents any integer of 2 to 50,000; and each of R1 groups and R2 groups may be the same or different from each other. |
| Claim: |
3. The process for producing a cyclic silane compound according to claim 1, wherein the cyclic silane compound is a compound represented by the following formula (2): [chemical expression included] wherein R1 and R2 represent the same meanings as in formula (1); n represents any integer of 1 to 20; R1 and R2 may be the same or different from each other; and each of R1 groups and R2 groups may be the same or different from each other. |
| Claim: |
4. The process for producing a cyclic silane compound according to claim 1, wherein the cyclic silane compound is decamethylcyclopentasilane. |
| Claim: |
5. The process for producing a cyclic silane compound according to claim 1, wherein the transition metal belonging to Group 8 of the periodic table is iron and the transition metal belonging to Group 11 is copper. |
| Claim: |
6. A process for producing a cyclic carbosilane compound, which comprises 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. |
| Claim: |
7. The process for producing a cyclic carbosilane compound according to claim 6, wherein the chained polysilane is a compound represented by formula (1). |
| Claim: |
8. The process for producing a cyclic carbosilane compound according to claim 6, wherein the cyclic carbosilane compound is 6- to 8-membered cyclic carbosilane compounds. |
| Claim: |
9. The process for producing a cyclic carbosilane compound according to claim 6, wherein the transition metal element is titanium, manganese, iron, cobalt, or palladium, and the element belonging to Groups 12 to 15 of the periodic table is aluminum, silicon, zinc, cadmium, tin, antimony, lead, or bismuth. |
