Synthesis and characterization of new tetraborylalkene

Although there are several studies about inorganic boron compounds; there are only few examples about organoboran compounds. In this study we aimed that supply lack of them. Tetraboryleten was synthesised with reaction of catechol substitued diboran and diboryl acetylene. It was synthesised by Siebert et all. Tetraboryleten is very stable because it doesn't have leaving group. In this study we synthesised reactive borylalkene from reaction of boriranlydeneborane and tetramethoxydiborane. Tetraborylalkene can convert to boran polyhedral in polar solvent. This polyhedral structure was characterised with 1H-, 13C- and 11B-NMR spectroscopy teqhnics. We keep trying to get single crystal for X-Ray structural analysing. Boron polyhedral have potential importance to industry in this study we showed that it. The result of similar studies were expected that can be synthesised different type of diborate and diboretane were obtained.
