【発明の名称】アルカリ金属のジアリールホスフィドおよびシクロアルキルジアリールホスフィン類の製造
Document Type and Number:
Japanese Patent JP2001509473
Kind Code:
A
Abstract:
(1) Alkali metal diarylphosphides are formed by mixing triarylphosphine with, and preferably introducing triarylphosphine into, a two-phase mixture one or more alkali metals, preferably a mixture or alloy of sodium and potassium, in an anhydrous organic liquid diluent in the presence of molecular hydrogen. (2) To form a cycloalkyldiarylphosphine, at least a portion of the reaction mixture formed as in (1) (or alkali metal diarylphosphide recovered therefrom) and cycloalkyl mesylate or tosylate are mixed together and maintained under suitable reaction conditions. Reaction (2) is driven by the presence of residual sodium from reaction (1). Conduct of reaction (2) under a hydrogen atmosphere suppresses undesirable side reactions.
