Claims12
A method for producing a catalyst, which is obtained by first mixing a compound expressed by the following Structural Formula (1), a neodymium-containing compound, a sodium-containing compound, and a carbon structure;
- and after the first mixing, further second mixing a nitroalkane compound:
- wherein the catalyst is a heterogeneous composite metallic complex, in which the compound expressed by the Structural Formula (1) is coordinated with neodymium and sodium;
- and
- wherein the first mixing is conducted in an absence of water.

A method for producing an optically active anti-1,2-nitroalkanol compound, the method comprising:
- allowing an aldehyde compound and a nitroalkane compound having 2 or more carbon atoms to react in the presence of a catalyst to obtain the optically active anti-1,2-nitroalkanol compound,
- wherein the catalyst is obtained by first mixing a compound expressed by the following Structural Formula (1), a nitroalkane compound, a neodymium-containing compound, a sodium-containing compound, and a carbon structure;
- and after the first mixing, further second mixing a nitroalkane compound:
- wherein the catalyst is a heterogeneous composite metallic complex, in which the compound expressed by the Structural Formula (1) is coordinated with neodymium and sodium;
- and
- wherein the first mixing is conducted in an absence of water.
