With the publication of Ketenes, Thomas Tidwell has succeeded in producing a truly comprehensive, up-to-date introduction to the entire field of ketene chemistry. Coverage extends from the first example of this family of chemicals discovered in through the most recent findings of This single, affordable volume covers all aspects of.

Ketenes are valued by both practicing organic synthetic chemists and pharmaceutical researchers for their ease of preparation, high reactivity, and versatility of use.

[Thomas T Tidwell] -- "Ketenes, Second Edition is an updated version of the premier resource Ketenes II book this important class of compounds, and features a comprehensive, self-contained guide to all aspects of ketene chemistry.".

A ketene is an organic compound of the form R′R″C=C=O, where R and R' are two arbitrary monovalent chemical groups (or two separate substitution sites in the same molecule).

The name may also refers to the specific compound ethenone H 2 C=C=O, the simplest ketene. Although they are highly useful, most ketenes are used as reagents in a chemical.

Summary This chapter contains sections titled: Oxidation and Reduction of Ketenes Photochemical Reactions Thermolysis Reactions Cycloaddition Reactions of Ketenes Nucleophilic Addition to Ketenes E.

Ketenes in general are useful reagents for acylating alcohols, \(\ce{ROH}\), and amines, \(\ce{RNH_2}\), because the reactions involve additions; there are no by-products to be separated: Ketenes also can be used for the synthesis of cyclobutane derivatives through [2 + 2] cycloadditions with suitably active alkenes (Section D).

Ketenes are highly reactive electrophiles that are generated by Pcatalyzed oxidation of acetylenes. Initial epoxidation to the oxirene ring followed by spontaneous rearrangement to the ketene is the proposed mechanism (Ortiz de Montellano and Komives ) (Figure 9).Despite being electrophiles, ketenes generated in this manner are generally not considered as toxic.

Ketenes are also formed by elimination reactions of esters, and the reaction of acetylated cellulose with tetra-n-butylammonium fluoride in tetrahydrofuran has been suggested to result in ketene formation by an elimination reaction by the E1cB mechanism in which fluoride ion acts a general base to abstract the proton (Scheme ), as supported by kinetic isotope effect.

Ketenes are a large class of reactants favoring [2 + 2] cycloaddition with olefins. The MO analysis of ketene cycloaddition is rendered complicated and ambiguous by the simultaneous but independent interaction of the orthogonal orbitals of the ketene but may involve a [π 2 s + π 2 a] interaction as well.
