Novel synthetic approaches towards organic sulfur pentafluorides

将开发新的合成方法，以将SF 5 O-、新型SF 5CF 2 O-和SF 5 OSF 4-基团安装到有机基质中。改变底物，试剂和反应条件的结构，我们将系统地研究在合成新的含SF 5取代基的化合物家族中各自反应的选择性。通过芳基炔合成SF 5 O-芳烃将被进行，并且具有SF 5 O-阴离子的过渡金属盐将被用作相应的工具。使用SF 5C（O）F作为前体，可获得含SF 5CF 2 O的有机化合物。通过芳基-SF_4Cl与AgOSF_5或芳基-SF_3与SF_5OF的反应，可以合成含SF_5OSF_4基团的芳香体系。这项研究将通过提供以前无法获得的可能对生物化学，有机电子和聚合物感兴趣的产品来扩大高价值含SF 5化合物的范围。

New synthetic methodologies will be developed towards the installation of SF5O-, novel SF5CF2O-, and SF5OSF4-groups into organic substrates. Varying the structure of substrates, reagents, and reaction conditions we will systematically examine the selectivity of the respective reactions in the synthesis of new families of compounds bearing SF5-containing substituents. The synthesis of SF5O-arenes via arynes will be carried out and transition-metal salts with SF5O- anions will be applied as respective tools. Using SF5C(O)F as a precursor, SF5CF2O-containing organic compounds will be available. By reacting either aryl-SF4Cl with AgOSF5 or Aryl-SF3 with SF5OF, SF5OSF4 group containing aromatic systems can be synthesized. This study will expand the scope of the highly valued SF5-containing compounds by offering previously inaccessible products potentially interesting for biochemistry, organic electronics, and polymers.
