✦ Synopsis

Although the nucleophilicity/basicity at the phosphorus atom of the tetraphosphacubane 2 is reduced, apparently owing to the participation of the lone pairs of electrons in the PIC u bonds, stepwise oxidation of the phosphoms atoms with bis(trimethylsily1) peroxide or sulfur (in the presence of triethylamine) can be realized until all four phosphorus atoms have reacted to give products 10-17. When 2 was treated with a large excess of selenium at llO"C, only the triselenide 18 was obtained.
