General Description

Dichlorostyrene is a chemical compound with the formula C8H6Cl2. It is a derivative of styrene, which is a common building block in the production of polymers and plastics. Dichlorostyrene is a liquid at room temperature and is often used as a monomer in the production of copolymers and resins. It can also be used as a chemical intermediate in the synthesis of other compounds. Dichlorostyrene is considered to be toxic and may pose health risks if not handled and disposed of properly. It is important to follow safety precautions when working with this chemical.

Visible-Light-Mediated Z -Stereoselective Monoalkylation of β,β-Dichlorostyrenes by Photoredox/Nickel Dual Catalysis

Metal-catalyzed alkylation of 1,1-dihalovinyl moiety commonly suffers from both a lack of stereoselectivity and the overreaction leading to the dialkylation product. The methodology described herein features a new pathway to alkylate stereoselectively β,β-dichlorostyryl substrates to provide the Z -trisubstituted olefin only with fair to good yields. This cross-coupling reaction bears on the smooth and photoinduced formation of a C-centered radical that engages in a nickel-catalyzed organometallic cycle to form the key C sp2-C sp3bond.

Cross-coupling reactivity of 1,1-dichloroalkenes under palladium catalysis: Domino synthesis of diarylalkynes

An efficient synthesis of diarylalkynes was achieved from the domino cross-coupling reaction of 1,1-dichloroalkenes with triarylbismuth reagents under palladium-catalyzed conditions. Under the established palladium protocol, 1,1-dichloroalkenes demonstrated hitherto unknown remarkable cross-coupling reactivity with organometallic triarylbismuth reagents to furnish functionalized diarylalkynes.
