摘要

为了更好地了解可分离伯胺膦氧化物的稳定性，我们通过氧化相应的膦来合成了这一家族的新成员。具体来说，用过氧化氢或偏氯过氧苯甲酸处理之前报道过的空气稳定伯胺膦 (R)-2-膦酰-2'-甲氧基-1,1'-联萘、9,10-二氢-9,10-乙烯基蒽-9-基膦和 3-膦基-2-萘酚，生成新的伯胺膦氧化物。利用核磁共振、质谱、EA 和 X 射线晶体学对这些化合物进行了表征。这些氧化物在热歧化反应中得到了进一步研究，并作为带有辅助 η6 对伞花烃配体的半夹心 Ru(II) 复合物中的配体进行了研究。

Exploring the Stability of Primary Phosphine Oxides: Correlation with Primary Phosphine′s Air-Stability?

To better understand the stability of isolable primary phosphine oxides, new members of this family were synthesized through the oxidation of the corresponding phosphines. Specifically, the previously reported air-stable primary phosphines (R)-2-phosphanyl-2’-methoxy-1,1’-binaphthyl, 9,10-dihydro-9,10-etheno-anthracen-9-yl phosphine, and 3-phosphino-2-naphthol were treated with hydrogen peroxide or meta-chloroperoxybenzoic acid to yield the new primary phosphine oxides. The compounds were characterized using NMR, MS, EA, and X-ray crystallography. The oxides were further investigated in thermal disproportionation, and studied as ligands in half-sandwich Ru(II) complexes bearing an auxiliary η⁶-p-cymene ligand.
