 Project objective

Multiple bonds have an enourmous impact on our lives as they are extremely useful functionalities in important industrial chemical transformations and products. The new millennium has witnessed considerable progress in the chemistry of main group compounds with multiple bonds. In case of elements other than carbon, the utilization of bulky ligands, with the appropriate steric and electronic effects, is a crucial factor in the stabilization of such species. Nevertheless, heteronuclear compounds containing triple bonds between the heavier elements of Group 13 and Group 15 are so far unknown. This proposal will address this knowledge gap by the use of donor-acceptor interactions to stabilize such compounds. The hypothesis rests not only in the stabilization provided by the Lewis base species but also on the electronic features enforced by them. This proposal will utilize the tools of experimental and computational chemistry in tandem, as an efficient and predictive strategy to gain synthetic access to the hitherto unknown triple bonds. These structures will present a multifunctional character, by having two pi-bonds, a lone pair on the Group 15 element, and Lewis base donors. Thus, given the unique bonding situation, they are expected to serve as innovative reagents for the activation of organic small molecules, as well as excellent metal-free catalysts and versatile coordination ligands toward transition metals. Furthermore, the heteroatomic triple bond motif is expected to provide unprecedented precursors for growing high-quality III-V semiconductor films. Therefore, the specific aims of this project are: (i) to comprehensively design the syntheses of these unique compounds; (ii) to develop and exploit their reactivity and; (iii) to harvest their potential in materials science. Achieving these aims will have a tremendous impact on various areas of academic and industrial interest ranging from catalysis and energy storage materials to photovoltaic devices.
