synthesis of allenylselenonium salts and their reactivities are described. The corresponding allenyl methyl selenides were alkylated with methyl trifluoromethanesulfonate to afford the desired compounds. Their reactions with active methylene carbanions produced furan, dihydrofuran or methylene cyclopropane derivatives via the Michael addition of nucleophiles to the selenonium salts.
描述了烯丙基硒鎓盐的首次合成及其反应性。将相应的烯丙基甲基硒化物用三氟甲磺酸甲酯烷基化,得到所需化合物。他们与活性亚甲基碳负离子的反应通过将亲核试剂迈克尔加成到硒鎓盐上生成呋喃,二氢呋喃或亚甲基环丙烷衍生物。
