This species reacted smoothly with electrophilic substrates such as acylhalides, α-bromocarbonyl compounds, diaryliodonium salts, α,β-unsaturated carbonyl compounds to afford the corresponding organic selenides in high yields.展开更多
Reduction of diaryldiselenides by the system of Cp2TiCl2/Bu'MgBr/THF gave the nucleophilic arylselenium complex. They reacted with diaryl iodonium salts to afford unsymmetrical diaryl selenides in high yields.
