| titleOfInvention | Cyclobutene production method |
| abstract | The purpose of the present invention is to produce cyclobutene containing a halogen atom with a high conversion ratio (yield) and high selectivity. This method, for producing the cyclobutene represented in general formula (1) (in the formula, X 1 , X 2 , X 3 and X 4 are the same or different, and represent a hydrogen atom, a halogen atom, or a perfluoroalkyl group. Y represents a halogen atom), involves a step for subjecting the cyclobutane represented by general formula (2) (in the formula, X 1 , X 2 , X 3 , X 4 and Y are as described above. X 5 and X 6 are the same or different and represent a hydrogen atom, a halogen atom, or a perfluoroalkyl group) to a desorption reaction, wherein the desorption reaction step is performed in the presence of a base, in a closed reaction system, or, the desorption reaction step is performed with the reaction temperature greater than or equal to 20°C, the reaction pressure greater than or equal to 0 kPa, and in the presence of a base. |
