College of Arts & Sciences Senior Honors Theses

Bis-thiosemicarbazones are an important class of ligands for the synthesis of transition metal complexes with applications in medicine and electrochemistry.^1,2 Among the most studied of these complexation ligands is diacetyl-2,3-bis(N⁴-methyl-3-thiosemicarbazone) (denoted as ATSM, 1, Figure 1).^2,3 Derivatives of 1 with various amines in place of the methylamine of ATSM have previously been reported, including diacetyl (N⁴-methylthiosemicarbazone-N⁴′-dimethylthio-semicarbazone) (denoted as ATSM/DM, 2).⁴ In this work, we pursue the development of a library of ATSM derivatives with a variety of functionalized pendant amines with a range of electronic and steric …
