Abstract
o-phenylene-bis(dialkyl- or diarylphosphines) or o-dialkyl (phosphino phenyl diarylphosphines) of general formula <FORM:0877592/IV (b)/1> are prepared by reacting in an inert atmosphere a dialkyl- or diarylchlorophosphine with an o-halogen substituted phenyl organometallic compound to give an o-halogen substituted phenyl dialkyl or phenyl diaryl phosphine, replacing the halogen with an alkali metal and reacting the resultant product with a dialkyl- or diarylchlorophosphine. The o-halogen-substituted phenyl organometallic compound may be the Grignard compound, o-halogen substituted phenyl magnesium bromide or o-halo-lithio-benzene, and the halogen formed in the first stage is replaced by lithium prior to the second stage. In an alternative one stage process a dialkyl- or di-arylchlorophosphine is reacted with an o-phenylene dialkali metal phosphine e.g. o-phenylene dilithium. Methyl, ethyl or phenyl phosphines are specified and mixed substituents may be formed by using a different dialkyl or diaryl chlorophosphine in the second stage. Examples describe the preparation of o-phenylene bis(diethylphosphine) by both the one and two stage processes, and of o-diethylphosphino phenyl diphenylphosphine by the two stage process. The products form co-ordination compounds with metals, which may be extracted thereby from solutions of their salts. Specification 859,741 is referred to.
