Answer 1

this is a condensation reaction between dimethyl amine C and pt fuopiophenone . thi veu follows the mechanism :- :2-51 Cry -LÄCHE N - CH3 Lekcn3 T 1-2- takes the "The bride (0°) take up a proton from any "The Base B - ссии proton from the N nucleo hilic attack of the love pair of amine on the electroprilie carbonye group N- CH3 - CH3 The 6-OH) gp is again protonated by some prolon in the solvent. OP Bo) 640" McRCHE CH The bace takes up the protone from ß carbon to give encamine ho is lost as to give are imine Enamine product product.
