Abstract

Ketenes have intrigued chemists with their unusual physical properties and their unique spectrum of chemical reactivity.[1] Ketenes are usually prepared by thermolysis, pyrolysis or in a stoichiometric manner from acyl chlorides using base-promoted elimination reactions.[2] Synthesis of ketenes from α-diazoketones by menas of the Wolff rearrangement [2d] is also noteworthy. However, all these synthetic methods have severe limitations and involve ...
