3. 2. Efficient and High-Yielding Routes to Diaryliodonium Salts

   Författare :Marcin Bielawski; Berit Olofsson; Stockholms universitet; []

   Sammanfattning : This thesis summarizes three novel and general reaction protocols for the synthesis of diaryliodonium salts. All protocols utilize mCPBA as oxidant and the acids used are either TfOH, to obtain triflate salts, or BF3•Et2O that gives the corresponding tetrafluoroborate salts in situ. LÄS MER
