Abstract

A synthesis method of a compound having a partial structure represented by following formula (21) or a tautomer thereof, the method comprising reacting at least one of a ligand and a dissociation product thereof with an iridium compound at a room temperature or at an elevated temperatures in the presence or absence of a solvent or in the presence or absence of a base:

Claims (18)

1 . A synthesis method of a compound having a partial structure represented by following formula (21) or a tautomer thereof, the method comprising:

reacting at least one of a ligand and a dissociation product thereof with an iridium compound at a room temperature or at an elevated temperatures in the presence or absence of a solvent or in the presence or absence of a base:

2 . A synthesis method of a compound represented by following formula (23), the method comprising:

reacting at least one of a ligand and a dissociation product thereof with an iridium compound at a room temperature or at an elevated temperatures in the presence or absence of a solvent or in the presence or absence of a base:

wherein R 11 and R 12 each represents a substituent; R 13 , R 14 and R 15 each represents a hydrogen atom or a substituent; m 1 represents an integer of from 0 to 4; and m 2 represents an integer of from 0 to 6.

3 . A synthesis method of a compound represented by following formula (24), the method comprising:

reacting at least one of a ligand and a dissociation product thereof with an iridium compound at a room temperature or at an elevated temperatures in the presence or absence of a solvent or in the presence or absence of a base:

wherein R 11 and R 12 each represents a substituent; m 1 represents an integer of from 0 to 4; m 2 represents an integer of from 0 to 6; Z 2 represents an atomic group which forms an aryl ring or a heteroaryl ring; Z 3 represents an atomic group which forms a nitrogen-containing heteroaryl ring; and n 1 represents an integer of from 1 to 3.

4 . The synthesis method according to claim 1 ,

wherein the iridium compound is selected from the group consisting of iridium chloride (III), trisacetyl acetonate iridium (III), potassium hexachloroiridate (III) and potassium hexachloroiridate (IV).

5 . The synthesis method according to claim 1 , which uses a mixed solvent of 2-methoxyethanol and water as the solvent.

6 . The synthesis method according to claim 1 ,

wherein the reaction is conducted in a stream of nitrogen.

7 . The synthesis method according to claim 1 , further comprising:

processing with an aqueous solution of hydrochloric acid.

8 . The synthesis method according to claim 1 , further comprising:

purifying through a silica gel column chromatography.

9 . The synthesis method according to claim 1 , which uses sodium methoxide as the base.
