Synthesis Of Novel Alkaline Earth Tosylate Complexes Through Donor Studies, Adam J. Brooks

Renée Crown University Honors Thesis Projects - All

Salt metathesis has become a critical reaction pathway in organometallic chemistry; however, for alkaline earth metals this process is hindered by the need of highly pure and expensive metal iodides as starting materials. This contribution highlights recent attempts to identify inexpensive reagents for salt metathesis. Alkaline earth-tosylates can be prepared cost effectively using p-toluenesulfonic acid in one-pot reactions in water. The coordinated water molecules can be removed by gentle heating under vacuum. The anhydrous tosylates, however, have major solubility limitations as the result of extensive aggregation networks. The goal of this study was to increase the solubility of the tosylates …
