Methodologies for the functionalization of phosphaalkenes Mes*P=CHal2 were developed. Lithiation with n-butyllithium yielded carbenoids Mes*P=CLiHal which were reacted with various electrophiles such as acid chlorides, carbonyl compounds, and metal halides. The dihalophosphaalkenes were also converted to monohalophosphaalkenes; the latter proved to be suitable for Stille-type cross coupling reaction with Grignard reagents. New phosphaalkenes of the type (E)-Mes*P=C(H)Ar with a variety of functionalities were obtained in high yield and isomeric purity.
