Synthesis of Polyfunctional Ketenimines and 1-Azadienes use of Tert -Butyl Isocyanide and Acetylenic Esters in the Presence of 3-Chloropentane-2,4-Dione
The 1:1 reactive intermediate generated by the addition of tert-butyl isocyanide to dialkyl acetylenedicarboxylates was trapped by 3-chloropentane-2, 4-dione to yield polyfunctionalised ketenimines and 1-azadienes.
