Title:
親水性ポリマー担体担持酸化オスミウム
Document Type and Number:
Japanese Patent JP4133337
Kind Code:
B2
Abstract:
A carrier for carrying an osmium oxide comprising an aromatic polyolefin having a group shown by the general formula Ä1Ü: - A'-O(-A-O)n-R (wherein, A is an alkylene group; A' is a direct link or an alkylene group; R is an aryl group; and n is an integer of 1 to 10), an osmium oxide carried by the carrier for carrying an osmium oxide and a method for producing the osmium oxide carried by said carrier, are disclosed. Since the osmium oxide carried by the carrier of the present invention has a group having hydrophilic property, on an oxidation reaction and an asymmetric oxidation reaction, particularly in a heterogeneous solvent system, the osmium oxide carried by the carrier of the present invention enables to produce a diol compound easily and in a high optical yield. And the osmium oxide carried by the carrier of the present invention can be used safely and effectively even for an oxidation reaction etc. with using a compound which has been difficult to react in a nonaqueous solvent.
