摘要: The stability of a number complexes dialkylzinc compounds R2Zn with N,N,N′,N′-tetramethylethylenediamine (TMED) and the potentially π-bonding ligand 2,2′-bipyridine (Bipy) has been compared using dielectric constant titration technique. R2Zn·TMED decreases in expected order: Me > Et iso-Pr tert-Bu. reversed sequence: < tert-Bu observed for R2Zn·Bipy complexes. It is concluded that predominant factor determining latter type
