1,4-Carbonyl-carbonyl interactions
Es wird gezeigt, dass die IR-Spektren gewisser 1,4-Diketone und 1,4-Ketoester abnorm hohe Carbonylfrequenzen aufweisen, was auf das Vorhandensein eines intramolekularen Feldeffekts zwischen den beiden Carbonylgruppen in diesen Verbindungen hindeutet. Die ungewohnlichen Stabilitatsverhaltnisse an C-20 der 16,22-Dicarbonyl-Steroide sind vermutlich auf die gleiche 1,4-Carbonyl-Carbonyl-Einwirkung zuruckzufuhren.
