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

摘要

Reactions of Cp~*_2Zn_2 with sterically demanding bis(iminodi-(phenyl)phosphorano)methanes LH (LH = CH_2(Ph_2P=NR)_2 (R = Ph L~1H, SiMe_3 L~2H, 2,6-i-Pr_2C_6H_3 (Dipp) L~3H) at ambient temperature occurred with elimination of Cp~*H and subsequent formation of the homoleptic complex L~]_2Zn_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.
