Tetramethyldibismuthine, 1, tetraisopropenyldibismuthine, 15, 1,1′-bibismolane, 16, and tetrakis(2-methyl-1-propenyl)dibismuthine, 17, have been prepared from the reaction of the corresponding tertiary bismuthines with sodium in liquid ammonia followed by treatment with 1,2-dichloroethane. Tetraphenyldibismuthine, 4, was prepared by an analogous route from diphenylbismuth chloride. While all the dibismuthines are red in solution, 1, 15, and 16 freeze to blue solids. Compounds 4 and 17 form red solids. The Raman, UV, and mass spectra of the dibismuthines are discussed. The dibismuthines thermally decompose to form bismuth metal and corresponding tertiary bismuthine. The reactions of tetramethyldibismuthine with iodine, bromotrichloromethane, benzyl bromide, hydrochloric acid, and butyllithium have been explored. The reactions afford products in which the Bi-Bi bond has been cleaved.
DARSTELLUNG UND SPECTROSKOPISCHE UNTERSUCHUNGEN VON METHYL- UND ISOPROPYLANTIMONHALOGENIDEN

Halogenations of iPr3Sb yield the dihalides iPr3SbX2 X=Cl, Br, I.These compounds decompose thermally to iPrX and iPr2SbX.Halogenations of iPr2SbX produce unstable trihalides iPr2SbX3, which eliminate iPrX to give iPrSbX2.By this procedure only the bromides and iodides iPr2SbX and iPrSbX2 X=Br, I can be obtained in useful yields and purities.Pure iPrSbCl2 and iPr3Sb are products of exchange reaction of iPr2SbCl.The purity of the known methylcompounds Me2SbX X=Cl, Br, I obtained by decomposition of Me3SbX2 has been examined.MeSbI2 and Me3Sb are formed from Me2SbI.Previously unpublished ir-, 1H-nmr-, and ms-data of iPr3SbX2, R2SbX and RSbX2 R=Me, iPr, X=Cl, Br, I are discussed.
