摘要
Organoselenium reagents are powerful tools for the preparation of small organic molecules.A simple preparation of polystyrene-supported（E）-1-bromo-2-selenoethylene was reported.In the presence of NiCl2（PPh3）2 catalyst,polystyrene-supported（E）-1-bromo-2-selenoethylene reacted with different Grignard reagents to offer（E）-1,2-disubstituted ethenes or trisubstituted ethenes.The evident advantages of this reaction are easy operations,odorlessness,good yields of the products.
Organoselenium reagents are powerful tools for the preparation of small organic molecules. A simple preparation of polystyrene-supported （E）-1-bromo-2-selenoethylene was reported. In the presence of NiCl2 （ PPh3 ） 2 catalyst, polystyrene-supported （E） -1-bromo-2-selenoethylene reacted with different Grignard reagents to offer（E）-1 ,2-disubstituted ethenes or trisubstituted ethenes. The evident advantages of this reaction are easy operations, odorlessness, good yields of the products.
