Intermediate snapshot on the insertion reaction of isocyanates into the Zn–Cp* bond of dizincocene Cp*₂Zn₂

Abstract

Heteroleptic Zn(i) complexes Cp*Zn–Zn(N(R)C(Cp*)O) with η4-coordinated tethered Cp* ligand represent snapshots of isocyanate insertion reactions into Zn–Cp* bonds. Their bonding nature was analysed by single crystal X-ray diffraction and computational calculations.

“…During the course of the reaction one Cp* ligand was protonated and cleaved off. 37 The remaining [ZnCp*] + fragment was bulky enough to provide steric shielding of the Zn atom. [38][39][40] Compound 3 crystallizes in the monoclinic space group P2 1 / n with one molecule in the asymmetric unit (Fig.…”
