Stereoselective synthesis of (E,E)-1-arylseleno-substituted 1,5-dien-3-ynes

Rongli, Zhang,Minhua, Jiang,Mingzhong, Cai

experimental part, p. 101 - 103 (2009/07/18)

Sonogashira coupling of (E)-1-iodo-2-arylselenoethylenes 1 with (trimethylsilyl)acetylene gave (E)-1-arylseleno-4-(trimethylsilyl)but-1-en-3- ynes 2, which underwent desilylation to afford (E)-1-arylselenobut-1-en-3-ynes 3 in high yields. (E,E)-1-Arylsele
