The compliance of the metal framework should in general be included when strain energies are estimated for metalclusters.
当估计金属簇的应变能时,通常应包括金属框架的顺应性。

Metallacarborane diene π-complexes. I. Synthesis of rhodacarboranes with a η2,η3-2-methylenenorbornadienyl ligand at the rhodium vertex
photochemical reaction of SF6 with phosphines, which selectively produces difluorophosphoranes and phosphine sulfides. Computational and experimental studies show that the π(Ar) → σ*(SF6) charge-transfer excitation of a preformed R3P⋯SF6 complex is the initial activation step. Using triphenylphosphine, the decomposition of SF6 was carried out in a solvent-free, scalable process, giving a 3 : 1 mixture of
SF 6的化学活化因其可能用作化学合成中廉价且安全的试剂而引起了相当多的关注。当与技术应用后强效温室气体的处理相结合时,这种过程变得特别有吸引力。在此,我们报道了SF 6与膦的光化学反应,该反应选择性地产生二氟正膦和硫化膦。计算和实验研究表明,预先形成的 R 3 PSF 6复合物的 π(Ar) → σ*(SF 6 ) 电荷转移激发是初始激活步骤。用三苯膦,分解SF 6在无溶剂、可扩展的过程中进行,得到二氟三苯基正膦和三苯基硫化膦 (TPP-Fluor) 的 3:1 混合物,用于醇和羧酸的脱氧氟化以及制备常见的六氟磷酸盐。
