Hydrazone synthesis

Sciencemadness Discussion Board

11/8/2017Hydrazone alpha-protons can still be abstracted giving E1cB products This is how SAMP/RAMP alkylations work This is of course down to which deprotonation occurs faster and is that fastness fast enough What could be expected is that the hydrazone NH deprotonation will be faster than alpha-deprotonation nevertheless both processes are possible
