Graceful degradation : The reaction of the [(Me 3 Si) 3 Si] − ion with white phosphorus results in a new phosphorus‐based dianion (see scheme; R=Si(SiMe 3 ) 3 ), apparently arising from the unexpected aggregation of two [RP 4 ] − units into a P 7 nortricyclic core with an exo anionic P atom. The formation of this dianion sheds new light on the mechanism(s) of P 4 degradation by nucleophiles and the ability of silyl substituents to direct product formation.
