General Description

1,1-di(o-tolyl)ethylene is a chemical compound with the molecular formula C16H14. It is a colorless liquid with a faint odor, and it is insoluble in water but soluble in organic solvents. 1,1-DI(O-TOLYL)ETHYLENE is commonly used as an intermediate in the production of dyes and pigments, as well as in the synthesis of pharmaceuticals and other organic compounds. It is also used as a stabilizer in polymers and as a reaction initiator in polymerization processes. 1,1-di(o-tolyl)ethylene is considered to have low toxicity, but exposure to high levels may cause irritation to the skin, eyes, and respiratory system. Additionally, it may pose a risk to the environment if released in large quantities.

Synergistic combination of visible-light photo-catalytic electron and energy transfer facilitating multicomponent synthesis of β-functionalized α,α-diarylethylamines

A synthetic strategy with the visible-light photo-catalytic synergistic combination of electron and energy transfer processes has been developed. The mild reaction conditions allow the radical-radical cross-coupling phenomenon for the multicomponent synthesis of β-arylsulfonyl(diarylphosphinoyl)-α,α-diarylethyl-amines from readily available arylsulfinic acids (diarylphosphine oxides), 1,1-diarylethylenes and arylazides.

Studies on the 1,2-migrations in Pd-catalyzed negishi couplings with JosiPhos ligands

(Chemical Equation Presented) We report an initial investigation with the goal of determining the factors that control the 1,2-migration in the Negishi cross-coupling, which is promoted by palladium catalyst systems generated with JosiPhos ligands. Severa
