Aliphatische tertiäre Amine werden durch Ozon in z. T. vorzüglichen Ausbeuten in Aminoxyde übergeführt. Aus Thioäthern entstehen mit 1 Mol. Ozon Sulfoxyde, mit zwei Moll. Ozon Sulfone. Die Ausbeuten liegen zwischen 80 und 100 %. Aus Disulfiden entstehen Thiosulfonate.

SummaryAnnular compounds containing two PAuP-entities are prepared by reaction of (trialky1phosphine)gold (I) halogenides with diphosphines. With bis (dimethylphosphin0)methane (DMPM), 1,2-bis (dimethy1phosphino)ethane (DMPE) and 1,3-bis (dimethy1phosphino)propane (DMPP) we obtained the following 8-, 10-and 12-membered annular binuclear complexes: [Au (DMPM)I2C1, . H20, (DMPP)],Cl, and [Au (DMPP)],(SbF6)2 as identified by conductivity measurements, 'H-and 3'P-NMR. spectra and extinction curves. Their absorption spectra differ from those of the isolated linear PAuP-complexes mainly by a very strong band at low energy which is absent in the latter. There is a strong interaction between the PAuP-entities only in certain excited electronic states and an understanding of all transitions is only possible, if both chromophores PAuP and (PAUP), are taken as a basis of interpretation. Bands of the same spectrum belong apparently to two different electronic systems.The absorption spectra of isolated linear and annular ylide-complexes containing one and two CAuC-entities, respectively, show quite the same behaviour.
