Abstract
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-Arylseleno-substituted 1,5-dien-3-ynes 5 could be synthesised stereoselectively via Sonogashira coupling of (E)-1-arylselenobut-1-en-3-ynes 3 with (E)-vinyl iodides 4.
