General Description

2,6-dichloro-3,5-dimethylcyclohexa-2,5-diene-1,4-dione, also known as paraquat, is a chemical compound commonly used as an herbicide. It is highly toxic to humans and animals, and exposure to even small amounts can be fatal. Paraquat works by disrupting the photosynthesis process in plants, causing them to die. In the body, it can cause severe damage to the lungs, kidneys, liver, and other organs, leading to respiratory failure, organ failure, and ultimately death. Due to its high toxicity, paraquat is tightly regulated and its use is restricted in many countries. It is considered a hazardous substance and proper safety precautions must be taken when handling it.

Iron-Catalyzed Radical Methylation of Activated Alkenes with tert -Butanol as the Methyl Source

A free-radical-initiated methylation/addition/cyclization of N -arylacrylamides and a methylation/addition/elimination of quinines have been developed in which t -BuOH is used as a methyl source. These reactions provide effective and selective methods for the synthesis of various methylated oxindoles and quinones in moderate to good yields.

Kinetic isotope effects for electron-transfer pathways in the oxidative C-H activation of hydrocarbons

Fast hydrogen atom transfers from various methylbenzenes (ArH) to photoactivated quinones Q* show primary kinetic isotope effects k(H)/k(D) of 2.4-5.6. The quantitative effects of added inert salt on the kinetics and on the yields of the intermediate cation radical ArH(+*) demonstrate that hydrogen transfer proceeds via a two-step sequence involving an initial electron transfer to form the ion-radical pair [ArH(+*), Q(-*)] which subsequently undergoes proton transfer according to the electron-transfer mechanism in Scheme 1.
