Chemistry of Organic Sulphur, Selenium, and Tellurium Compounds

这项研究计划得到了有机合成计划的支持。将继续研究含有硫、硒和碲的化合物的化学方面，这些方面有可能对有机金属和光学传感器等多个领域产生影响。有机硫化学的研究将着重于以下几个方面：L。有机硫化学将研究很少被探索的硫代羰基化合物的化学(例如，硫代对苯二酚、硫代酸酐)。其他可能是圆周率供体的硫杂环(例如，四硫富瓦烯衍生物、聚噻吩类等)或LB片候选人也将成为调查对象。2.有机硒化学将集中在新的有机硒试剂、新的含硒的pi供体和硒的羰基衍生物上。3.有机碲化学将合成新的含碲TTF和乙烯类TTF衍生物。将尝试合成众所周知的1，2，3-噻二唑的碲类似物。将对新的含碲官能团的化学进行研究。

This research program is being supported by the Organic Synthesis Program. Aspects of the chemistry of compounds containing sulphur, selenium and tellurium will be pursued which have the potential to impact on a diverse number of areas such as organic metals and optical sensors. The investigation in organochalcogen chemistry will emphasize the following areas: l. Organosulfur Chemistry The chemistry of little explored types of thiocarbonyl compounds will be studied (e.g., thioquinones, thionoanhydrides). Other sulfur heterocycles which are potential pi donors (e.g., tetrathiafulvalene derivatives, polythiophenes, etc.) or LB film candidates will also be objects of investigation. 2. Organoselenium Chemistry Attention will be focussed on new organoselenium reagents, new selenium-containing pi donors, and selenocarbonyl derivatives. 3. Organotellurium Chemistry New tellurium-containing TTF and vinylogous TTF derivatives will be synthesized. Attempts will be made to synthesize tellurium analogs of the well known 1,2,3-thiadiazoles. The chemistry of new tellurium-containing functional groups will be investigated.
