The Diels-Alder adducts 2–6 are prepared in good yields (67–98%) by [2 + 4] cycloaddition of the selenocarbonyldifluoride F2CSe (1) to a 1,3-diene e.g. isoprene, 2,3-dimethyl-1,3-butadiene, cyclopentadiene, pentamethylcyclopentadiene and 1,3-cyclohexadiene. The only by-product, (F2CSe)x, is formed by the polymerization of 1. The new compounds 2–6 are stable at room temperature; they have been characterized
的狄尔斯-阿德耳加合物2 - 6是由[2 + 4] F中的selenocarbonyldifluoride的环加成以良好的收率(67-98%),制备2 CSe(1)向1,3-二烯例如异戊二烯,2,3- -二甲基-1,3-丁二烯,环戊二烯,五甲基环戊二烯和1,3-环己二烯。唯一的副产物(F 2 CSe)x通过1的聚合反应形成。新化合物2 – 6在室温下稳定。它们已经通过元素分析(C,H)以及MS,NMR和IR光谱进行了表征。
