Freshly generated solutions of iodine azide (IN3) and iodine isocyanate (INCO) in acetonitrile or carbon tetrachloride add oxidatively to tertiaryaryl derivatives of group VB elements, Ar3M (Ar = Ph, p-tolyl, p-ClC6H4 or p-FC6H4, and M = As, Sb or Bi) and diaryltellurium(II), Ar2Te (Ar = Ph or p-CH3OC6H4) at −10°C to −5°C to give stable covalent monomeric products, Ar3MIX and Ar2TeIX, respectively
新生成的溶液碘叠氮化物(IN 3)和碘乙腈或四氯化碳氧化添加到VB族元素的tertiaryaryl衍生物的异氰酸酯(INCO)中,Ar 3 M(Ar为PH,p -甲苯基,p -ClC 6 ħ 4或p -FC 6 H 4和M = As,Sb或Bi)和二芳基碲(II),Ar 2 Te(Ar = Ph或p -CH 3 OC 6 H 4)在-10°C至-5°C至分别得到稳定的共价单体产物Ar 3 MIX和Ar 2 TeIX(其中X = N 3或NCO)。伪卤化物基团与M的键合方式已经通过固态红外光谱确定。Ar 3 MI(N 3)无法与CS 2反应,但与PhNCY(Y = O或S)反应得到环状四唑衍生物。在Ar 2 MIX和Ar 2 TeIX与假卤化银[AgX'(X'= NCO或NCS)]的复分解反应中也观察到相反的行为。四有机化合物R 4 M(M = Sn或Pb,R = Ph或对甲苯基)和Bu 3
