Direct [3 + 2] radical cycloaddition of methylenecyclopropanes and elemental chalcogens (S, Se, Te) can readily occur under simple thermal conditions, providing an efficient, practical method for preparation of useful but not easily accessed methylene-1,2-dichalcogenolanes.
亚甲基环丙烷和元素硫族元素(S,Se,Te)的直接[3 + 2]自由基环加成反应可以在简单的热条件下轻易发生,为制备有用但不易获得的亚甲基1,2-二氟gen烷提供了有效而实用的方法。
