Formation of a Ph2PCH(BH3)P(BH3)Ph2 ligand via formal 1,2-borane migration

Abstract

The transfer of the anionic Ph(2)P(BH(3))-CH-P(BH(3))Ph(2) ligand from potassium to barium results in the subsequent formation of a tetranuclear barium cluster which contains the hitherto unknown isomeric form Ph(2)P-CH(BH(3))-P(BH(3))Ph(2) of the ligand.
