A new strategy for the synthesis of epoxides is presented. This process allows the direct synthesis of epoxides from alkenes and aldehydes through C-H functionalization and C-C/C-O bond formation.

Unlike aromatic polycarbonates, aliphatic polycarbonates (APCs) have been little explored commercially. However, their low toxicity and biodegradability make them excellent candidates for biomedical applications. Recently, they have also been investigated as thermoplastics, binders for photovoltaics, polymer electrolytes and adhesives. Part of this renewed attention stems from the possibility t...

Since the pioneering work1 of Furukawa in the late 1980s, some examples2 of nonracemic epoxidation have been reported using aromatic aldehydes and chiral sulfur ylides. Enantiopure oxiranes are versatile compounds for organic synthesis. They can be transformed3 into 1,2difunctionalized derivatives by nucleophilic ring opening reactions. Our group has recently developed4 an efficient asymmetric ...

A library of new dinuclear CeIV complexes the type [NEt4]2[Ce2X6(TP)(sol)2] (X = Cl, ODipp, OSiMe3; sol py, THF), where TP represents a family tetraphenolate ligands that control intermetallic distance, are readily made in good yields. The strongly stabilize cerium +4 oxidation state and allow incorporation alkylammonium cocations an “ate” complex formulation enables them to be used as soluble,...

For the production of cyclic carbonates from cycloaddition CO2 with epoxides, halogen pollution and product purity are two most common problems due to usage homogeneous halogen-containing catalysts such as ammonium salt alkali metal halide. Hence, development a novel, halogen-free efficient catalyst for synthesis high-purity is significant. Here, series acid–base bifunctional Ce1-xZrxO2 nanorod...

Azidolysis of epoxides followed by reduction of the intermediate azido alcohols constitutes a valuable synthetic tool for the construction of beta-amino alcohols, an important chemical functionality occurring in many biologically active compounds of natural origin. However, depending on conditions under which the azidolysis is carried out, two regioisomeric products can be formed, as a conseque...
