Green Chemistry: Synthesis and Hydrogenation of Substituted Chalcones Submitted by: Anahita Sanaie Partner: Ley Smith Date: December 1, 2008 TA: Sureyya Workstation 2T-202 CHM 2211L- 0789 Goal : To determine which functional groups are reduced in the catalytic hydrogenation of an α,β-unsaturated ketone. CHALCONE 7 Reactions : Synthesis of Chalcone Hydrogenation reaction: Data: Synthesis Reagents Mass Moles MW 4-methylbenzaldehyde 0.432 g 3.6 mmol 120 g/mol 4-chlorobenzophenone 0.543 g 3.53 mmol 154 g/mol NaOH pellets 0.382 g 9.53 mmol 40.1 g/mol Recrystalized Product (chalcone) Mass MW Melting Point % yield 0.13 g 256 g/mol 161° C 14.4 % Hydrogenation Reagents Mass Moles MW Recryst. Chalcone 0.1 g 0.39 mmol 256 g/mol Ammonium Formate 0.185 g 2.925 mmol 63.09 g/mol Pd/C 0.023 g 0.216 mmol 106.42 g/mol Hydrogenation product 0.09 g 0.35 mmol 256 g/mol Procedures: Synthesis : 0.432 g of 4-methylbenzaldehyde (3.6 mmol) was added to 0.543 g 4- chlorobenzophenone (3.53 mmol) in a 25 ml Erlenmeyer flask and stirred until there was a homogeneous liquid. 0.382 g of sodium hydroxide pellets were stirred with 0.5 ml
