## CPC

- C07F 5/02: Boron compounds
- C07F: ACYCLIC, CARBOCYCLIC OR HETEROCYCLIC COMPOUNDS CONTAINING ELEMENTS OTHER THAN CARBON, HYDROGEN, HALOGEN, OXYGEN, NITROGEN, SULFUR, SELENIUM OR TELLURIUM (metal-containing porphyrins C07D487/22)

## Abstract

In synthesis of hexaalkylborazine represented by the chemical formula 2 from a borazine compound represented by the chemical formula 1, a borazine compound represented by the chemical formula 1 is reacted with an alkene compound, in the presence of a catalyst. Wherein R1s may be the same or different and each R1 represents an alkyl group; and each R2 represents a hydrogen atom or an alkyl group, and at least one of R2s represents a hydrogen atom; and R3s may be the same or different and each R3 represents an alkyl group.

## Claims

### Claim 1

A method for producing hexaalkylborazine, wherein hexaalkylborazine represented by the chemical formula 2 is synthesized by a reaction of a borazine compound represented by the chemical formula 1 with an alkene compound, in the presence of a catalyst:
wherein R1s may be the same or different and each R1 represents an alkyl group; and each R2 represents a hydrogen atom or an alkyl group, and at least one of R2s represents a hydrogen atom:
wherein R1s and R3s may be the same or different and each R1 and R3 represents an alkyl group.

### Claim 2 (depends on 1)

A method for production according to claim 1, wherein the catalyst is a metal catalyst.

### Claim 3 (depends on 1)

A method for production according to claim 1, wherein the reaction is carried out in the presence of a compound which becomes a ligand of a metal complex.

### Claim 4 (depends on 2)

A method for production according to claim 2, wherein the reaction is carried out in the presence of a compound which becomes a ligand of a metal complex.
