Claims

1. The following formula (1): 【Chemistry 1】 (In formula (1), A is an alicyclic site that may be replaced. L is an ethylene group, a norbornylene group, or a decahydro-1,4:5,8-dimethanonaphthylene group. R １ A cyclic carbonate represented by (where is an aliphatic hydrocarbon group having 1 to 20 carbon atoms, which may be substituted, or an aromatic hydrocarbon group having 6 to 20 carbon atoms, which may be substituted).

2. The cyclic carbonate according to claim 1, wherein A is a cyclohexane-1,2-diyl group.

3. The aforementioned R １ The cyclic carbonate according to claim 1, wherein the group is a cyclohexyl group, an adamantyl group, or a decyl group.

4. The following formula (1): 【Chemistry 2】 (In formula (1), A is an alicyclic site that may be replaced. L is an ethylene group, a norbornylene group, or a decahydro-1,4:5,8-dimethanonaphthylene group. R ２ A method for producing a cyclic carbonate, represented by (where is an aliphatic hydrocarbon group having 1 to 20 carbon atoms which may be substituted, or an aromatic hydrocarbon group having 6 to 20 carbon atoms which may be substituted), The following formula (2): 【Transformation 3】 A cyclic carbonate represented by formula (2), where A is an optionally substituted alicyclic moiety and E is an optionally substituted C1-C20 alkenyl group, or The following formula (2'): 【Chemistry 4】 A cyclic carbonate represented by formula (2') (wherein A' is an unsaturated alicyclic moiety that may be substituted), Formula (3) below: H-S-R １ (3) (In formula (3), R １ A method for producing a mixture comprising the step of mixing and stirring a mixture containing a thiol compound represented by ), wherein is an aliphatic hydrocarbon group having 1 to 20 carbon atoms which may be substituted, or an aromatic hydrocarbon group having 6 to 20 carbon atoms which may be substituted.
