Stereoselective Synthesis of (E)-1-Halo-2-arylselanylethylenes via Hydrozirconation of Arylselanylethynes
Zhu, Liu-Sheng,Huang, Zhi-Zhen,Huang, Xian
, p. 112 - 113 (2007/10/03)
Hydrozirconation of arylselanylethynes gives zirconium(iv) complexes, which are trapped with iodine or N-bromosuccinimide to afford (E)-1-halo-2-arylselanylethylenes.
