Novel hybrid aluminium(iii)-catalen complexes as highly active catalysts for lactide polymerisation: towards industrial relevance.

Herein, we report a series of highly active Al(iii)-complexes based on a novel hybrid ligand: the catalen. Their application in the production of polylactide under both solution, and industrially preferred melt conditions, is demonstrated. Potential structural diversification to broaden initiator scope is discussed.
