Tuning the selectivity of P₄ reduction at alkaline-earth metal centres.

ABSTRACT: Reduction of P₄ with β-diketiminate Mg^I complexes, (BDI)MgMg(BDI), depends strongly on the bulk of the ligand. Whereas superbulky BDI ligands gave selective reduction to P₄ ^2- in a butterfly conformation, reduction with a less bulky ligand gave various products among which P₈ ^4- had a realgar-type structure. The selectivity of P₄ reduction can also be controlled by metal choice. Reduction of P₄ with Ca^I synthons of general type (BDI*)Ca-X-Ca(BDI*) in which BDI* is a superbulky ligand and X is a bridging dianion (C₆H₆ ^2- < p-xylene^2- < N₂ ^2-) led to reduction of P₄ to the very common, stable Zintl anion P₇
