Abstract

The reactivity of the redox-active metal crown complex (BDI*)MgNa3N′′2 (VI), formally containing a Mg⁰ centre, with phosphine chalcogenides, R3P 00000000 00000000 00000000 00000000 11111111 00000000 11111111 00000000 00000000 00000000 Ch (Ch = O, S, Se, Te; R = Me, Et) was investigated (BDI* = HC[tBuC N(DIPeP)]2 with DIPeP = 2,6-Et2CH-phenyl). While all R3P Ch reagents could be reduced, only the heavier ones led to clean reduction to S²⁻, Se²⁻ and Te²⁻ anions which were captured in the metalla-cycle. The smaller S²⁻ anion can be stabilized by the tetrametallic MgNa3-crown but the larger Se²⁻ and Te²⁻ require a pentametallic MgNa4-crown. Reaction of the sulfide complex with N2O led to a rare thiohyponitrite cis-SNNO²⁻ anion which is trapped in the pentametallic MgNa4-crown. Experimental observations and bonding characteristics of all complexes are supported by an additional computational study.
