ketenes's Usage Examples:

When ketenes are formed in the presence of alkynes they proceed through pericyclic.

a highly reactive ketene compound: These ketenes can be isolated using flash vacuum pyrolysis (FVP).

products of the ketenes.

Diphenylketene, like most disubstituted ketenes, is a red-orange oil at room temperature and pressure.

rearrangement is the reaction of allylic ethers, amines, and thioethers with ketenes to give γ,δ-unsaturated esters, amides, and thioesters.

thesis topic was Studies of ketenes and their derivatives (1941).

Bellus–Claisen rearrangementThe Bellus–Claisen rearrangement is the reaction of allylic ethers, amines, and thioethers with ketenes to give γ,δ-unsaturated esters, amides, and thioesters.

Thioketenes are organosulfur compounds analogous to ketenes with the general formula R2CCS, where R is alkyl or aryl.

Ketene cycloadditions are the reactions of the pi system of ketenes with unsaturated compounds to provide four-membered or larger rings.

compounds which undergo [2+2] cycloadditions with the in situ generated ketenes.

Diphenylketene, like most disubstituted ketenes, is a red-orange oil at room temperature and.

Ketenes with strong electron-donating substituents mainly produce cis β-lactams, while ketenes with strong electron-withdrawing.

Halogen substituted ketenes (R1, R2) are often used in this reaction for their high electrophilicity.
