o-Triisopropylsiloxyaryl ketones and aldehydes smoothly reacted with the lithium salt of trimethylsilyldiazomethane to give o-triisopropylsiloxyphenylacetylenes which were easily converted to benzofurans by treatment with tetra-n-butylammonium fluoride. 3-Benzofuranmethanols were also obtained when the reaction was conducted in the presence of carbonyl compounds.
邻三异丙基硅氧芳基酮和醛与三甲基硅基二氮杂环丁烷的锂盐顺利反应,生成邻三异丙基硅氧苯乙炔,经四正丁基氟化铵处理后很容易转化为苯并呋喃。在有羰基化合物存在的情况下进行反应,还可以得到 3-苯并呋喃甲醇。
