Molecular structures are often influenced by aromatic stabilization and antiaromatic destabilization effects. In spite of nearly a century's effort-from Kekulé 1871 to Breslow and Dewar 1965-to synthesize cyclobutadiene, these attempts have proved to be unsuccessful [1-6]. Only theoretical chemistry was able to explain this failure by introducing the concept of antiaromaticity as a new phenomenon. The synthesis of these antiaromatic compounds has long been considered as desirable target of preparative chemistry in order to examine experimentally their species chemical properties, but only a few compounds could be prepared and studied. One of the examples may be the family of phosphole oxides exhibiting a slightly antiaromatic character [7-10]. At the same time, heterophosphetes, are of more considerable antiaromatic character and they manifest only as high energy intermediate or transition state (TS) [11-20]. In this paper, stability and thermodynamic, as well as kinetic properties of heterophosphetes and phosphole oxides are discussed.
