1,1-Diiodoalkenes 1 were readily prepared from carbonyl compounds 2 and diethyl diiodomethylphosphonate (3), generated in situ from commercial diethyl iodomethylphosphonate (4) or diethyl methylphosphonate (5). Starting from aldehydes, iodoacetylenes 6 could be obtained directly in situ by dehydrohalogenation of diiodoalkenes 1.
1,1-二碘烯1很容易通过羰基化合物2和二乙基二碘甲基膦酸酯3(由商业二乙基碘甲基膦酸酯4或二乙基甲基膦酸酯5原位生成)制备而得。从醛开始,可以通过二碘烯1的脱卤化氢反应直接原位得到碘乙炔6。
