Usage

Physical state

A colorless liquid with a faint odor, which suggests that it is a pure substance and not a gas or solid.

Solubility

Insoluble in water but soluble in most organic solvents, which means that it does not mix well with polar solvents but does mix well with nonpolar solvents.

Uses

Primarily used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds, which suggests that it is a versatile compound with a wide range of applications.

Reactivity

Can undergo addition reactions with various nucleophiles, which means that it can react with other compounds to form new products.

Safety

Flammable and can cause irritation to the skin, eyes, and respiratory system if not handled properly, which indicates that it is a hazardous substance that requires proper safety precautions.

Reactions of dichlorocarbene and arenesulfenyl chlorides with 3,4-epoxy-1-butene and vinylethylene carbonate

Reaction of 3,4-epoxy-1-butene with dichlorocarbene is accompanied by deoxygenation and yields a mixture of 1,1-dichloro-2-vinylcyclopropane, 2,2,2',2'-tetrachlorobicyclopropyl, and 2,2-dichlorocyclopropyloxirane. Arenesulfenyl chlorides react with 3,4-epoxy-1-butene to afford both Markownikoff and anti-Markownikoff addition products, whereas vinylethylene carbonate gives rise exclusively to the anti-Markownikoff adducts.
