- Аннотация: Heteroarylamido hafnium post‐metallocenes with [C,N,N] ligands were functionalized by the insertion of small electrophilic unsaturated molecules into the CAr−Hf bond of the ligand, which gave rise to various 1,1‐ and 1,2‐insertion complexes with the modified ligands of previously unknown [O,N,N], [N,N,N], [O,N,N,N], and [N,N,N,N] types. It was found that C1 symmetry of the starting complexes, in some cases, results in the formation of two diastereoisomers after 1,1‐ or 1,2‐insertion. Most of the obtained novel complexes were shown to form active catalysts for olefin polymerization in the presence of MAO (methylaluminoxane). Thus, a new approach to the feasible and easy “late stage” modification of the precatalyst structure has been suggested; it can be performed immediately prior to the polymerization tests without isolation and even in a high‐throughput manner.
