“…As with carbon-supported aluminum hydride systems, a common reactivity pathway is the hydroalumination of organic π-bonds. Given the plethora of new N -donor aluminum hydride systems reported in the past two decades, ,− this section will aim to focus on the new bonding motifs and reactivity pathways uncovered in this area.…”

This review serves to document advances in the synthesis, versatile bonding, and reactivity of molecular main group metal hydrides within Groups 1, 2, and 12−16. Particular attention will be given to the emerging use of said hydrides in the rapidly expanding field of Main Group element-mediated catalysis. While this review is comprehensive in nature, focus will be given to research appearing in the open literature since 2001.

“…It is in a liquid state at room temperature. Many organometallic compounds formed by this auxiliary ligand with aluminium (Liu et al, 2013) and zinc (Hsiao et al, 2012) or transition metals including Ti (Li et al, 2005), Zr (Hsu et al, 2012), Hf (Lee et al, 2011), Ga (Wang et al, 2013), In (Kuo et al, 2003, Y (Kuo et al, 2005) and Mo (Huang et al, 2001) have been reported and there are several reports of the crystal structures of organometallic compounds containing 2,5-bis[(dimethylamino)methylene]-1H-pyrrole as a ligand (Xia et al, 2002;Lee et al, 2011;Chang et al, 2011;Wang et al, 2012). However, although 2,5-bis[(dimethylamino)methylene]-1H-pyrrole has been prepared and studied for a long time, its crystal structure has not been reported so far.…”

With the development of the technology of ring-opening polymerization (ROP) rapidly, many novel aluminum complexes have been designed, synthesized, and applied in initiating ROP of cyclic esters and new stereoregular polymerization mechanism of lactide polymerization have been reported. In this review, the mechanism for ROP of cyclic ester, synthesis of aluminum complexes containing tetradendete ligand, tridentate ligand, bidentate ligand, and bimetallic complexes containing aluminum were reviewed. We hope to give some helpful information for designing aluminum complexes, improving activity, and stereoregularity of aluminum complexes.Keywords: ring-opening polymerization; cyclic ester; aluminum complexes; stereoregularity IntroductionAliphatic polyester is biodegradable and biocompatible materials, which prepared using ring-opening polymerization (ROP) of cyclic ester such as lactide, caprolactone. trimethylene carbonate, and other cyclic ester. [1,2] Due to effective influences of microstructure, molecular weight, and polydispersity indexes (PDIs) on polyester physicochemical properties, the controlled/living ROP for synthesis of polyester which enables the ready to control these parameters attracted an extraordinary amount of research recently.[3-6] During the last two decades, the improvement in catalyst makes it possible to design and synthesis of polyester.
