文摘

Reduction of [P₂N₂]ZrCl₂ (where [P₂N₂] = PhP(CH₂SiMe₂NSiMe₂CH₂)₂PPh) with KC₈ under argon generates the phosphorus phenyl bridged bimetallic complex where the bridging phenyl groups are formally reduced to bis(allyl) dianions. Similar reduction of [P₂N₂]NbCl caused the one-electron reduction of the phosphorus phenyl group to generate a cyclohexadienyl moiety via a C-C bond formation between the ipso carbons of the two phenyl groups.
