A Cp*Co(CO)I2 catalyzed Mizoroki-Heck coupling of alkenes and aryl halide is established at feasible reaction conditions. The Cp*Co(III) catalyst excellently work to couple the aryl iodide and alkene, and produce up to 94% yield of the coupling

Paragraph 0046-0050, (2019/02/06)
The invention discloses a diarylethene synthesis method without transition metal catalysis. The method comprises the following steps: a cinnamic acid derivative and aryl trifluoroborate are subjectedto a decarboxylation coupling reaction in a solvent under the action of an oxidizing agent, postprocessing is performed after the reaction, and diarylethene is obtained. K2S2O8 is adopted to promote acatalytic system in the synthetic method, and a free radical coupling reaction can be performed directly under the condition that no ligand, transition metal or alkali is added. The method has widersubstrate range and higher yield; the method is simple to operate, reaction conditions are mild, and large-scale application is facilitated.

A phosphanamine-functionalized trimethoxysilyl compound (DPPPA) was synthesized and reacted with magnetic nanoparticles in order to synthesise a novel magnetic reusable phosphanamine ligand (PAFMNP) for application in transition metal-catalyzed coupling reactions. The Pd complex of PAFMNP (Pd-PAFMNP) was found to be an efficient heterogeneous catalyst for the Heck reaction of aryl chlorides. Only 1.0 mol% of catalyst was needed to accomplish the Heck reaction of the aryl chlorides. The catalyst was reusable at least 5 times without a significant decrease in its catalytic activity.
