Mind your "P"s: Silylated P-heterocyclic biradicals activated tetrahydrofuran to give the corresponding 4-siloxybutyl-substituted 1,3-diphosphacyclobutane-2,4-diyls via ring-opening of the solvent molecule. Reductive P-C bond cleavage was found as an alternative approach to 1,3-diphosphacyclobuten-4-yl anion. Redox properties of the new P-heterocyclic biradicals were discussed in terms of hitherto unknown substituent effects.
注意你的“P”：硅烷化的 P-杂环双自由基活化四氢呋喃，通过溶剂分子的开环反应得到相应的 4-硅氧基丁基取代的 1,3-二磷杂环丁烷-2,4-二基。发现还原 P-C 键断裂是 1,3-二磷杂环丁烯-4-基阴离子的另一种方法。根据迄今为止未知的取代基效应，讨论了新的 P-杂环双自由基的氧化还原性质。
