Abstract
A method for producing a diphosphine monoxide represented by a general formula (2), including: allowing a diphosphine represented by a general formula (1) to react with water in the presence of a metal catalyst, an oxidizing agent, and a base to selectively oxidize the diphosphine. In the general formulas (1) and (2), R1, R2, R3, R4, and Y are the same as defined in the description.
Claims8
A method for producing a diphosphine monoxide represented by a general formula (2), the method comprising:
- allowing a diphosphine represented by a general formula (1) to react with water in the presence of a metal catalyst, an oxidizing agent, and a base to selectively oxidize the diphosphine,
- wherein in the general formula (1) and the general formula (2), R1, R2, R3 and R4 each independently represent an aryl group optionally having a substituent, a heterocyclic group optionally having a substituent, an alkyl group optionally having a substituent, or a cycloalkyl group optionally having a substituent, and Y represents an alkylene group optionally having a substituent or a divalent arylene group optionally having a substituent.
