“…Thus, other than the homogeneous catalyst, the DMC catalyst may generate complicated active sites with different kinetics. Despite these expected cons, the heterogeneous DMC catalysts possess high stability and, reusability after separating from products, and they may enable the fast and large-scale production and the selective product formation …”

“…Despite these expected cons, the heterogeneous DMC catalysts possess high stability and, reusability after separating from products, and they may enable the fast and large-scale production and the selective product formation. 35 To compare with a homogeneous anionic ROMPB of glycidol using potassium alkylate as a catalyst, attempts have been made to resolve the following points raised on the heterogeneous ROMBP using a DMC catalyst: (i) catalyst activity, (ii) type of active sites, (iii) mechanistic pathway, (iv) decisive reaction parameters, and (v) the resultant polymer structures. For this, we have chosen 2 different catalysts DMC−DEM-and DMC−EAA-bearing diethyl malonate (DEM) and ethyl acetoacetate (EAA), respectively, as complexing agents (CAs).…”

“…Metal–organic frameworks (MOFs) are a new and promising class of crystalline porous hybrid materials composed of metal ion clusters linked by organic linkers via strong covalent bonds to form extended networks. Due to their outstanding features, including high internal surface area, large porosity, structural tunability, potentially high density of active sites, and acceptable thermal and chemical stability, , MOFs have attracted much attention in the field of heterogeneous catalysis. They have been used as effective supports to immobilize metal nanoparticles in their pores and on the functional groups within the backbone of the framework, which prevents aggregation of the nanoparticles …”

“…Double metal cyanide (DMC) complexes are inorganic coordination polymers generated by two metal atoms linked via cyanide bridges [26]. They are strictly Lewis acidic and highly stable solid materials [27] that have been employed as catalysts for the ROP of propylene oxide (PO) since the 1960s [28,29].…”

“…Nevertheless, solid catalysts for the ROP of lactones are still underexplored, as compared to homogeneous ones, thus effective catalytic systems for lactone polymerization are still in demand. Double metal cyanide (DMC) complexes are inorganic coordination polymers generated by two metal atoms linked via cyanide bridges [26]. They are strictly Lewis acidic and highly stable solid materials [27] that have been employed as catalysts for the ROP of propylene oxide (PO) since the 1960s [28,29].…”
