“…In 2012, Sajiki and coworkers published the Pd/C catalyzed dechlorination of polychlorinated biphenyls in the presence of Mg metal/MeOH at room temperature. 149 A broad range of aryl chlorides with a variety of functional groups was tolerated in their reaction protocol. The authors proposed a reaction pathway which was similar to their previously reported reductive deoxygenation of aryl triflates.…”

Defunctionalization has a direct impact on the synthesis of value added products (e.g. biomass degradation). In synthetic chemistry it enables the functional group to act as a transient directing group. In this mini review, we have described the chronological development of metal assisted defunctionalization reactions from the stoichiometric to the catalytic stage with their application in synthetic organic chemistry. The proposed catalytic cycles of the transformations have been described to make this review comprehensible.

“…Later the same group successfully eliminated the need of flammable hydrogen gas for the dechlorination reaction after the addition of Mg metal. Wide varieties of both electron‐donating and electron‐withdrawing substituted aryl chlorides were applicable . Ganguly's group described the Pd/C‐catalyzed hydrogenolysis of allyl phenyl ethers and allyl coumarinyl ethers via cleavage of C−O bond in combination with ammonium formate at room temperature [Eq.…”

Palladium on charcoal( Pd/C)h as lots of salient merits:( i) it is ac heap andc ommercial source of palladium, (ii)i ts hows efficientc atalytic activity even without ligands,( iii)a saheterogeneous catalyst it is easily recycledm any times by simple filtration,a nd (iv) it is applicablet oag reat number of reactions and substrates,a lthough it is eventually less efficient than homogeneous Pd catalysts containing some sophisticated ligands.T hisr eview recalls the main background ands ummarizes the progress made essentially during the last twelve years in Pd/C-catalyzed organic synthesis since the reviews by Felpins group andSekiin2 006.

“…Studies have shown the successful liquid-phase hydrodechlorination of chlorinated benzenes on a variety of supported heterogeneous palladium catalysts, including Pd-on-Al 2 O 3 (Scüth and Reinhard 1998;Benítez and Del Angel 2000;Kopinke et al 2004;Hashimoto et al 2005;Mackenzie et al 2006;Gómez-Quero et al 2010a, 2010b), Pd-on-SiO 2 (Benítez and Del Angel 2000; Jujjuri and Keane 2010), Pd-on-C (Benítez and Del Angel 2000;Yakovlev et al 2000;Xia et al 2004;Janiak and Okal 2009), and other supported palladium catalysts (Lassová et al 1999;Aramendía et al 2002). Supported heterogeneous palladium catalysts have also been shown to successfully catalyze the HDH of chlorinated phenols (Hoke et al 1992;Shindler et al 2001;Keane 2003a, 2003b;Pozan and Boz 2008;Xia et al 2009;Gómez-Quero et al 2010a, 2010b, chlorinated ethylenes (Kovenklioglu et al 1992;Munakata et al 1998;Lowry and Reinhard 2000;Concibido et al 2005Concibido et al , 2006Concibido et al , 2007Mackenzie et al 2006;Ordóñez et al 2010), and polychlorinated biphenyls (Forni et al 1997;Kume et al 2008;Ishihara et al 2012).…”

This thesis is dedicated to my parents. My mother's unwavering love and support has made the completion of this thesis possible. While my father will not have the opportunity to read this manuscript, he always encouraged my scholastic endeavors and taught me a love of learning that has followed me throughout my life. His life and scholarship will always be a source of inspiration for me. ACKNOWLEDGMENTS This thesis would not have been possible without my advisor, Dr. Jeffrey Cunningham, who has provided guidance and mentorship throughout my graduate school experience. I am deeply grateful for his positive attitude, critical eye for detail, and continued support throughout this process. I would also like to thank Dr. James Mihelcic, who inspired me to make the transition to the field of environmental engineering, and who has provided continued support over the past two years. Lastly, I would like to thank the members of my committee for the time they invested in reviewing my work.
