MANUFACTURING METHOD OF MONOCHLOROETHYLENE CARBONATE

PROBLEM TO BE SOLVED: To provide a manufacturing method of industrial monochloroethylene carbonate by carrying out a photoreaction between ethylene carbonate and chlorine gas. SOLUTION: A manufacturing method of monochloroethylene carbonate is characterized in that by using a flow type photochlorination apparatus that comprises a reaction case for reacting a liquid while supplying liquid, a support stage for supporting by tilting the reaction case in such a way that the liquid flows through its own weight, a light irradiation section for transmitting light for performing a photochlorination reaction by irradiating light on the reaction case, and a temperature control unit for carrying out the photochlorination reaction by controlling the temperature of the reaction case on the reaction case, ethylene carbonate is introduced from the liquid supply part into each channel groove, chlorine gas is introduced into the gas circulation part from the gas supply port, and light is radiated from the light irradiation section is provided, and thereby the problem was solved.

Terminal aziridines by addition of Grignard reagents or organoceriums to an (α-chloro)sulfinylimine

Reaction of N-(2-chloroethylidene)-tert-butylsulfinamide with Grignard reagents or organoceriums gives terminal N-tert-butylsulfinyl aziridines in good yields and (mainly with organoceriums) good diastereomeric ratios. Oxidation of terminal N-tert-butylsu
