= Ph, C6H4Me-o, -m, -p, or C6H4Cl-p) react with seleniumdioxide suspended in benzene or in solution in ethanol to give triarylphosphine oxides, PR3O, and triarylphosphine selenides, PR3Se, or selenium, depending on the phosphine, the relative proporfions of the reagents, and the solvent. Triarylarsines do not react with SeO2 in ethanol, but reactions in benzene suspension give triarylarsine oxides

tris(m-tolylarsane), bis(diphenylarsano)ethane, and tris(naphthyl)arsane have been synthesized. All of the new complexes, 1-4, have been fully characterized by means of ¹H NMR and ¹³C NMR spectroscopy and single crystal X-ray crystallography. The structures of complexes 1-4 have been determined from X-ray diffraction data. The linear molecules have an average bond distance between gold-arsenic and gold-chlorine of
合成了一系列LAuCl型的配合物,其中L =三(对甲苯基戊烷),三(间甲苯基戊烷),双(二苯基亚氨基)乙烷和三(萘基)砷烷。所有的新配合物1-4,都已经通过1 H NMR和13 C NMR光谱学以及单晶X射线晶体学进行了充分表征。配合物1-4的结构已经由X射线衍射数据确定。线性分子在金-砷和金-氯之间的平均键距分别为2.3390Å和2.2846Å。亲油相互作用在复合物1和3中很明显,而复合物2和4没有显示任何这种相互作用。分子间金相互作用键的长度受分子的电负性影响。使用B3LYP函数在DFT级别计算的计算值与实验结果非常吻合。
triruthenium clusters, Ru3(CO)9(μ‐arphos)AsPh3 (1), Ru3(CO)9(μ‐arphos)As(m‐C6H4Me)3 (2), and Ru3(CO)9(μ‐arphos)As(p‐C6H4Me)3 (3) were synthesized via thermal reactions of Ru3(CO)10(μ‐arphos) with different tertiary arsine ligands [AsPh3, As(m‐C6H4Me)3, As(p‐C6H4Me)3]. All these complexes were fully characterized by elemental analysis, FT‐IR, NMR spectroscopy, and single‐crystal X‐ray diffraction.
