All-metal aromaticity and antiaromaticity

Article Abstract:

The new developments in the aromaticity and antiaromaticity in all-metal or metalloid cluster systems are important for developing a unified chemical bonding theory. The concepts of aromaticity and antiaromaticity can be valuable tools in explaining structure, stability, chemical bonding and other molecular properties of many isolated metal clusters, as well as metal clusters incorporated in organometallic compounds or in solid materials.

Reactions of othophthalaldehyde with nucleophiles

Article Abstract:

An attempt is to contribute to the understanding of the solution chemistry involved in the determination of amino acids that are dealt with ternary mixtures containing OPA, thiol, and amino acid. The conclusions about the course of reactions involved based on identification of products or variation of concentration of a single component with time and limited evidence about the equilibria assumed to be involved is highlighted.
