Insertion Reactions of Heterocumulenes with Zincocene Cp* 2 Zn

Zincocene Cp* 2 Zn reacts with carbodiimides C(N R ) 2 with insertion into the Zn–Cp* bond and formation of [(Cp*C(N R ) 2 ] 2 Zn [ R = Et ( 1 ), i Pr ( 2 ), Cy ( 3 )]. In addition, the reaction of Cp* 2 Zn with CS 2 under dry conditions gives (Cp*CS 2 ) 2 Zn ( 4 ), whereas in the presence of a small amount of water [Zn 4 (μ 4 ‐O)(S 2 CCp*) 6 ] ( 5 ) is obtained. Compounds 1 – 4 were characterized by NMR ( 1 H, 13 C) and IR spectroscopy as well as elemental analysis and single‐crystal X‐ray diffraction ( 2 – 4 , 5 of poor quality). The solid‐state structure of 5 is comparable to the carboxylate complex previously obtained from the reaction of Cp* 2 Zn with CO 2 .
