“…5,6 In particular aluminum alkoxides and aluminum alkyl complexes have displayed good catalytic activity toward the ring-opening polymerization of lactide and cyclic esters. [13][14][15][16] Several aluminum alkoxide catalysts have been successfully applied for the stereoselective ROP of rac-LA by Spassky et al [17][18][19][20][21] In most cases, the actual initiators/catalysts in the living polymerization systems are aluminum alkoxides, which can be pre-prepared by the reaction of ligated aluminum…”

Aluminum alkyl complexes have very useful applications as catalysts or reagents in small molecule transformations and as cocatalysts in olefin polymerization. This short review focuses on some recent developments in the design, synthesis and structure of aluminum(iii) alkyl complexes supported by various ligands bearing nitrogen, oxygen, sulfur or phosphorus atoms, and their catalytic applications in the ring-opening polymerization (ROP) of cyclic esters. The coordination chemistry of the Al metal centre and the catalytic activity changes of the complexes caused by ligand modifications are also discussed.

“…The significance of alcohols lies in their accessibility as precursor materials, derived from both the petrochemical industry and renewable biomass feedstocks. [28][29][30][31] Using alcohols as starting materials, transition metal-catalyzed borrowing hydrogen (BH) reactions have provided a straightforward process for creating C-C bonds, resulting in water as the only green byproduct. [32][33][34][35][36][37][38][39][40] In this BH process, the alcohol is dehydrogenated with the help of a transition metal catalyst and forms a reactive carbonyl intermediate.…”
