Any bees ever dream this one with piperonal?
How about the variation of this reaction in toluene with a Dean Stark water trap?
In this variation, after the reaction, the toluene layer is transfered to a 3 neck RBF along with water, Iron metal powder and iron chloride with a mechanical stirrer, addition funnel with HCL and is refluxed while dripping HCL into the flask. The yield of P2P (from both procedures) is supposed to be much better than the nitroalkene synthesis where the water trap is not used. But what about MDP2P?
Any insight is GREATLY appreciated!!! I did use TFSE but had no luck with ethylenediamine.
