Bis{(2-diphenylphosphino)phenyl}mercury: a novel bidentate ligand and transfer reagent for the o-C6H4PPh2 group
Abstract
The compound [Hg(o-C6H4PPh2)2] behaves as a trans-spanning bidentate ditertiary phosphine in its PdCl2 complex, the two metal atoms being forced into close contact; the palladium(0) complex [Pd{(o-Ph2PC6H4)2Hg}2] undergoes reductive elimination on heating with formation of the coupled product o-Ph2PC6H4C6H4PPh2-o.
