Abstract

A new general synthesis of β-keto-enolates is described, whereby diketen is caused to react with various organic derivatives of aluminium, boron, and tin. Diketen thus reacts differently from its monomer (which affords C-acetyl derivatives). This is attributed to the unsymmetrical structure of the dimer. The symmetrical phenyl isocyanate dimer behaves similarly to its monomer in its reaction with trisdimethylaminoborane. The β-keto-enolates are ...
