Abstract
Designing a catalyst for random copolymerization by ring-opening polymerization (ROP) is an actual task. In the present work, we report the synthesis of aluminum complexes (R′ = Et, R′′ = Ph (5); R′ = Bn, R′′ = Ph (6); R′ = t-Bu, R′′ = Ph (7); R′ = R′′ = Ph (8)] based on diamidoamine pro-ligands. The reactivity of complexes in the ROP of ε-caprolactone (ε-CL) was studied. The highest activity was shown by complexes 5 and 8, containing phenyl groups at the terminal nitrogen atoms of the ligand in the ROP of ε-CL. Also, complex 5 was an effective initiator of copolymerization of 2-(benzyloxycarbonyl)-2-methyltrimethylene carbonate (TMCR) and L-lactide (L-LA) which led to the formation of a random copolymer.
期刊介绍：
Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
