Abstract

Positively phosphorus: A solvent-free melt system (P4/Ph2PCl/GaCl3) represents a powerful medium for the functionalization of the P4 tetrahedron to form new cationic phosphorus-rich organophosphorus cage and cluster systems, such as [Ph2P5]+, [Ph4P6]2+, and [Ph6P7]3+ (see picture), by insertion of [Ph2P]+ into P[BOND]P bonds.
