Oxo organic chemistry
WebA lot of drugs in the market are small organic molecules and as a student of medicinal chemistry, biochemistry, pharmacy, pharmacology or medicine, knowledge of the different functional groups is crucial. Functional groups are specific substituents or moieties, composed of an atom or a group of atoms, within molecules that possess similar … Web9.1.3 The Oxo Clusters. In cluster chemistry, the oxo clusters are usually generated by combination of central atoms and oxygen ligands with three forms: the O 2− anion, OH − group, and O-donor of ligands, while the central atoms include nonmetals and metals. Therefore, the oxo clusters can be divided into two types, oxo nonmetal and oxo ...
