WebFor the reduction reaction with NaBH4, calculate the theoretical yield and percent yield of the crude product after liquid-liquid extraction. Assume the ketone is the limiting reactant, … H2salen may be synthesized by the condensation of ethylenediamine and salicylaldehyde. Complexes of salen with metal cations may be made without isolating it from the reaction mixture. This is possible because the stability constant for the formation of the metal complexes are very high, due to the chelate effect.
