Arsadiphosphabenzenes 1,l-Bis[(diphenylphosphanyl)methyl]ethene (3) reacts with PC13 or AsCl, in the presence of SnC12 as a reducing agent to form cationic heterocycles in which the two newly generated phosphonium centers are bridged by two-coordinate, negatively charged phosphorus (4a) or arsenic (
