Research Abstract

The design and syntheses of organic molecules bearing new functional groups are one of the most important problem in synthetic organic chemistry. If unprecedented molecules can be made, not only new insight conserning the structure and conformations of the molecules can be studied but also new synthetic reactions can be developed. These new results further involve several new concept.
On the basis of the above background the attention has been paid to a series of chalcogenocarboxylic acid derivatives where the oxygen atom of carboxylic acids is replaced with the heavier atoms in the same low of the periodic table such as sulfur, selenium, and tellurium. Their new synthetic methods were developed, and their properties were disclosed.
For example, new and efficient synthetic methods of selenoamides and selenothioic acid S-esters have been established. The compounds having selenotellurocarboxyl group have also been synthesized for the first time. The new reactions using these compounds were tested, and synthetic reactions leading to a variety of organoselenium compounds were provided. The studies on their spectroscopic properties and stability led the general trend of the structures and stability of the compounds, although it is qualitative.
Additionally, the reactivity of selenocarboxylic acid Se-arsenic esters have been examined. As a result, new diorganoarsinic acid salts were isolated, and their structure was analyzed.
