摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.

摘要:The present invention provides an industrial process for effectively and advantageously preparing optically active 1-substituted amino-2,3-epoxypropanes useful as intermediates for preparing agricultural chemicals and medical products from optically active 1-substituted amino-2,3-propanediols used as raw materials. The present invention also provides useful intermediates. Specifically, an optically active 1-substituted amino-2,3-propanediol (1) is reacted with an orthoacid ester (2) or thionyl chloride (3) to produce a cyclic optically active compound (4), and then a compound (5) containing a halogen atom is prepared by reaction with a ring-opening reaction agent having an ability to introduce a halogen atom X. Finally, an optical active 1-substituted amino-2,3-epoxypropane is prepared by ring-closure reaction in the presence of a base.
