What is diketene made from?

In the absence of a reactive substrate, ketene combines with itself to form diketene, a β-lactone used industrially to prepare derivatives of acetoacetic acid, such as ethyl acetoacetateand acetoacetamides. The higher ketenes are generally synthesized by elimination of hydrogen chloridefrom acyl chlorides.

What are the industrial uses of ketene?

Ketene is remarkably reactive; it combines with compounds containing an easily replaced hydrogen atom to yield derivatives of acetic acid. The only important industrial use of ketene itself is its reaction with acetic acid to form acetic anhydride. Ketene reacts with aldehydes and ketones to form enol acetates or β- lactones.

What is the name of the simplest ketene?

The simplest ketene (CH 2 C O, ethenone) also is named just ketene. Ketenes are reactive compounds that dimerize to diketenes. Some ketenes such as ethenone dimerize, forming a lactone (oxetan-2-one).

How do you convert ketene aminal 197 to ketene 199 in acetone?

The reaction of the ketene aminal 197 with α,β-unsaturated acyl isothiocyanates 198 has been achieved in acetone to give ketene aminals 199 bearing an acyl thioamide substituent at the β-position <1998HCA718>. Yields varied from 59% to 87%.
