Abstract

Bis (2-phenylphosphinoethyl)phenylphosphine, PhP(CH2CH 2PPh2)2, reacts with lithium in tetrahydrofuran to give the corresponding lithium bis (2-diphenylphosphidoethyl) phenylphosphine, Li2[PhP(CH2CH2PPh) 2]. The lithium diphosphide is identified by NMR spectroscopy and further characterized through arylation with excess brombenzene to reform the starting phosphine, PhP(CH2CH2PPh2) 2. Initial reactivity studies of the diphosphide, PhP(CH 2CH2PPh)2 -2, with some alkylhalides are also described.
