Ionic liquid tethered post functionalized ZIF-90 framework for the cycloaddition of propylene oxide and CO2

, 2016
A novel heterogeneous one-component catalyst was developed by the covalent post functionalization of zeolitic imidazolate framework-90 (ZIF-90) with a pyridinium based ionic liquid (IL) to generate IL supported ZIF-90 (IL-ZIF-90).

Gadolinium-Based Metal–Organic Framework as an Efficient and Heterogeneous Catalyst To Activate Epoxides for Cycloaddition of CO2 and Alcoholysis

, 2017
Development of heterogeneous catalysts for the cycloaddition of CO2 with epoxides to prepare cyclic carbonates is a hot topic in the field of CO2 transformation. Herein, a rare-earth-metal gadolinium-based metal–organic framework (Gd-MOF) was synthesized

Photocatalytic Regioselective and Stereoselective [2 + 2] Cycloaddition of Styrene Derivatives Using a Heterogeneous Organic Photocatalyst

, 2017
Photocatalytic [2 + 2] cycloaddition is a useful tool for the synthesis of cyclobutane derivatives, which contributes a large part to natural compound production. Usually, the [2 + 2] cycloadditions are catalyzed by transition-metal complexes.

Cycloaddition an Homofulvene

Angewandte Chemie, 1970
Die Homofulvene (Ia) bzw. (Ib) lassen sich in einer K-carbonat-Losung mit N-Chlorsulfonylisocyanat bei -60°C in einer Homo-[6+2]-Cycloaddition unter Inversion an C-6 zu den Addukten (IIa) bzw. (IIb) umsetzen.
