Abstract

1,6-Diiodohexa-1,3,5-triyne (3) and 1,8-diiodoocta-1,3,5,7-tetrayne (5) were prepared in yields of 64 and 75%, respectively, using a new method, allowing easy scale-up. Novel alkyne synthons, viz. 1-triisopropylsilyl-4-iodobuta-1,3-diyne (7) and 1-trimethylsilyl-4-iodobuta-1,3-diyne (8) were obtained in yields of 55 and 40%, respectively, from butadiyne in two-step reactions.
