Ligandenaustausch in Alkoxo/Halogenostiban-Systemen
摘要:
In Sb(OR)3/SbHal3 systems (R = Et, Pr, (i)Pr, Bu, (i)Bu, (neo)Pent; Hal = Cl, Br) a rapid exchange of ligands takes place. It is shown by ebullioscopic data that there is a random distribution in a system containing 7 different particles. The mixed alkoxohalogenostibanes are associated. The total association is estimated comparing the averaged experimental and statistical molecular masses. An ebullioscope of high precision is described.
