The synthesis of a remarkable cyclic bis(P-H lambda(5)-phosphorane) is reported. A stable phosphorus-heterocyclic biradical, 1,3-diphosphacyclobutane-2,4-diyl, sequentially accepts negatively and positively charged hydrogen atoms to afford 2,4-diphospha-1,3-cyclobutadiene with a diylidic structure containing two P-H bonds.
报道了一种引人注目的环状双（P-H λ⁵-磷叶立德）的合成。一种稳定的磷杂环双自由基，1,3-二磷杂环丁烷-2,4-二基，依次接受带负电荷和正电荷的氢原子，得到具有含两个P-H键的二亚基结构的2,4-二磷杂-1,3-环丁二烯。
