  Synthesis and Reactions of Bis (4,5‐benzo‐1,3‐dioxa‐2‐phospholano)dichlormethane

  摘要：

  AbstractThe title compound 3 was formed in the reaction of Cl2PCCl2PCl2 (2) with catechol in the presence of triethylamine. The reaction of 3 with tetrachloro‐o‐benzoquinone (TOB), 4, led to the σ3P/σ5P‐species 5, and the σ5P/σ5P‐species 6a/6b. 5 was stable only in solution, and its existence and identity are postulated on the basis of its 31P‐NMR spectrum. The structure of 6a/6b could not be assigned unambiguously to one isomer. The reaction of 6a/6b with water yielded the phosphorate 10. The structures of 3 and 10 were determined by single crystal X‐ray methods. A wide PCP angle (123.2°) was observed in 3. The cation of 10 is a centrosymmetric, protonated DMF dimer with OO 241.3 pm.
