Hydrogenation of a di-substituted chalcone. Chem 2311.
The catalyst used is excess H2 in 10% Pd/C, and methanol. This
produces 7 different possible products.
Mechanism: a) Propose two advantages of having the palladium metal delivered as a support on carbon instead of using elemental palladium metal? (see p. 148 of the manual for ideas) b) Whether hydrogen is prepared in situ, as in this experiment from ammonium formate, or delivered froma hydrogen gas cylinder, the mechanism of the catalytic reduction...

1) Predict the Products: Using line drawings with proper use of
dashed wedge and solid wedge notation where necessary, draw the
major organic products of the following reactions in the boxes
provided. If no reaction occurs write “no reaction” or “N.R.” in
the box. Include stereochemistry in your answers where appropriate.
If a product is racemic draw both enantiomers or write “racemic”
next to the structure. Assume all reagents written above and below
the arrows are present in excess unless...
