Magnetic Nickel-Containing Heterogeneous Catalysts for the Heck Reaction: Catalyst Design, Performance, and Sustainability. [PDF]
ChemistryOpenThis schematic outlines a general Heck coupling using magnetic nickel‐based catalysts. The reactants are mixed and heated to promote carbon–carbon bond formation and produce a substituted alkene product. After completion, an external magnet enables rapid separation of the nickel catalyst from the reaction mixture.

Toxicological characteristics of the cinnamic
Hygiene and sanitation, 2019 The toxic properties of the cinnamic alcohol with an aim of its hygienic rating are studied. DL for male rats, male and female mice are respectively 3300, 3000 and 2700 mg/kg. It refers to the substances of hazard class 3. The clinical picture of acute poisoning was characterized by the general depression, muscle relaxation, disorder of the movement ...
