The diaryldiselenides reacted with titanocene hydried (Cp_2TiH) generted from Cp_2TiCl_2/i-BuMgBr to give arylselenium complexes of titanocene. They reacted readily with diaryliodoiums salt to give unsymmetical diarylselenides.
The diaryldiselenides reacted with titanocene hydried (Cp_2TiH) generted from Cp_2TiCl_2 / i-BuMgBr to give arylselenium complexes of titanocene. It turned out that diaryliodoiums salt to give unsymmetical diarylselenides.
