Title:
CYCLIC PHOSPHINE COMPOUND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/075257
Kind Code:
A1
Abstract:
The present invention relates to a symmetric or asymmetric cyclic phosphine compound preparation method and, more specifically, comprises a step of reacting a cyclic phosphine compound and an organic halogen compound in the presence of a predetermined coupling agent. The present invention provides the symmetric or asymmetric cyclic phosphine compound preparation method, which is economical by enabling the use of a compound less expensive than that used in a conventional method and allowing reaction materials to have excellent storage stability, facilitates reaction control, generates less by-products such that productivity and yield can be improved, facilitates application on an industrial scale, and allows a synthesis pathway to have excellent extensibility or substitutability.
