Reactions of dizincocene with sterically demanding bis(iminodi(phenyl)phosphorano)methanes

Reactions of Cp* 2 Zn 2 with sterically demanding bis(iminodi(phenyl)phosphorano)methanes LH (LH = CH 2 (Ph 2 P&z.dbd;NR) 2 (R = Ph L 1 H , SiMe 3 L 2 H , 2,6- i -Pr 2 C 6 H 3 (Dipp) L 3 H ) at ambient temperature occurred with elimination of Cp*H and subsequent formation of the homoleptic complex L 1 2 Zn 2 1 and the heteroleptic complexes LZnZnCp* (L = L 2 2 , L 3 3 , L 1 4 ). 3 is the first structurally characterized heteroleptic organozinc complex with the zinc atoms in the formal oxidation state +1. Synthesis and X-ray crystal structures of homo- and heteroleptic Zn( i ) complexes.
