Creating Dynamic Nanospaces in Solution by Cationic Cages as Multirole Catalytic Platform for Unconventional C(sp)?H Activation Beyond Enzyme Mimics

Herein we demonstrate that, based on the creation of dynamic nanospaces in solution by highly charged positive coordination cage of [Pd6(RuL3)8]28+, multirole and multi-way cage-confined catalysis is accomplisha

Synthesis of 1,3-Diynes Using Calcium Carbide as an Alkyne Source

A simple method for the synthesis of 1,3-diynes from iodoarenes using calcium carbide as an alkyne source and air as an oxidant is described. A series of 1,4-diarylbuta-1,3-diynes were efficiently synthesized by this strategy. The salient features of this protocol are the use of inexpensive and easy-to-handle alkyne source, broad substrate scope, open-air condition, and simple operation procedure.

Leaf-like CuO nanosheets on rGO as an efficient heterogeneous catalyst for Csp-Csp homocoupling of terminal alkynes

In this work, the economic and well-defined leaf-like CuO nanosheets on rGO (CuO nanosheets/rGO) was synthesized by a convenient hydrothermal method. The morphology and chemical composition of CuO nanosheets/rGO were confirmed by XRD, SEM-EDS, TEM, HR-TEM, and XPS techniques. The CuO nanosheets/rGO was successfully applied as a high-performance heterogeneous catalyst in the homocoupling of 12 terminal alkynes, and the isolated yield of each product was more than 80%, except for propargyl alcohol. This catalyst could be reused five times with little activity loss. Thus, it is beneficial for green and sustainable development of organic synthetic chemistry.
