Diphosphine dichalcogenides

Tertiary phosphine chalcogenide Diphosphine dichalcogenide Diphosphine monochalcogenide... [Pg.287]

Related to these diphosphine dichalcogenides are the triphosphine trisulfides [R2P(S)]3CH (12) which can be prepared from lithiated methylene diphosphine disulfides upon treatment with thiophosphinic chlorides (Equation 9). Deprotonation of 12 with tBuLi gives a resonance-stabilised anion 13 containing a planar central carbanion whose charge is delocalised onto the three neighbouring phosphorus and sulfur atoms.32... [Pg.294]
