Syntheses of Unique Tris\(pyrazolyl)methane Ligands for the Preparation of New Mono- and Multi-metallic Compounds

南卡罗来纳大学哥伦比亚分校化学和生物化学系的Daniel L.Reger因其开发三(吡唑基)甲烷(TPM)配体的新金属络合物的工作而得到无机化学、生物无机和有机金属化学计划的支持。这些配体与三(吡唑基)硼酸盐密切相关，但制备起来要困难得多。Reger开发了合成TPM配体的新途径，如HC(Pz)3、HC(3，5-Me2pz)3、HC(3-Phpz)3、HC(3-tBupz)3和HC(3-iPrpz)3。连接的双官能团和多官能团吡喃甲烷配体，如C6H4[CH2OCH2C(PZ)3]2的所有三种异构体，都将成为合成具有特殊二维或三维超分子结构的配位聚合物的基石。TPM配体的金属络合物可能具有独特的反应活性或催化活性。配位聚合物，特别是那些含有两种不同金属的配位聚合物，将具有有趣的物理或电子性质。此外，几名研究生和教职员工，包括HBCU本科院校的同事，将有机会参与研究项目。

Daniel L. Reger, Department of Chemistry and Biochemistry, University of South Carolina at Columbia, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for his work developing new metal complexes of tris(pyrazoyl)methane (tpm) ligands. These ligands are closely related to tris(pyrazoyl)borates, but have been much more difficult to prepare. Reger has developed new synthetic pathways to tpm ligands such as HC(pz)3, HC(3,5-Me2pz)3, HC(3-Phpz)3, HC(3-tBupz)3 and HC(3-iPrpz)3. Linked bi- and poly-functional pyrazoyl methane ligands, such as all three isomers of C6H4[CH2OCH2C(pz)3]2, will form building blocks for the preparation of coordination polymers that have unusual 2-D or 3-D supramolecular structures. Metal complexes of tpm ligands may show unique reactivity or catalytic activity. The coordination polymers, especially those containing two different metals, will have interesting physical or electronic properties. In addition, several graduate students and faculty members, including coworkers from a HBCU undergraduate institution, will have the opportunity to participate in the research project.
