Dimethylbismuthanyl bromide, with the chemical formula (CH3)2BiBr, is an organobismuth compound that features a bismuth atom bonded to two methyl groups and a bromine atom. dimethylbismuthanyl bromide is a colorless, crystalline solid that is sensitive to air and moisture, and it is typically synthesized by reacting bismuth metal with methyl bromide. Dimethylbismuthanyl bromide is of interest in organometallic chemistry due to its potential applications in the synthesis of other organobismuth compounds and as a precursor in various chemical reactions. It is also notable for its role in studying the chemistry of bismuth, a relatively less explored element in organometallic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 7529-35-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,2 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7529-35:
(6*7)+(5*5)+(4*2)+(3*9)+(2*3)+(1*5)=113
113 % 10 = 3
So 7529-35-3 is a valid CAS Registry Number.

Preparation and properties of dibismuthines

Ashe III, Arthur J.,Ludwig Jr., Edward G.,Oleksyszyn, Josef

, p. 1859 - 1866 (2008/10/08)

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.
