摘要：

The title compound (6) may be conveniently synthesised via the three-stage route: [GRAPHICS] [GRAPHICS] In the first stage the alkyne PhC=CBr is also produced, and this undergoes reaction with iodine generated in the second stage to give the alkene (E)-PhCI=CBrI (10) (up to 9.5%). Other by-products formed in the second stage, depending on the conditions employed, are the 1,4-diyne PhC=CCF2C=CPh (12), isolated in 3.5% yield, and 1-iodo-2,3-naphtho-4-phenyltetrafluorocyclobutene (11), isolated in 11.5% yield. Mechanisms are advanced to account for all the products isolated.
