Tri(p-tolyl)bismuth dichloride, also known as tri(p-methylphenyl)bismuth dichloride, is a chemical compound with the formula [Bi(C6H4CH3)3]Cl2. It is a derivative of bismuth, a post-transition metal, and features three p-tolyl (p-methylphenyl) ligands attached to the central bismuth atom. The compound is characterized by its yellowish color and is typically used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and the synthesis of various organobismuth compounds. Tri(p-tolyl)bismuth dichloride is sensitive to air and moisture, and it is usually stored under an inert atmosphere to prevent decomposition. Its applications in chemical research and synthesis highlight its importance in the field of organometallic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 6729-64-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,2 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6729-64:
(6*6)+(5*7)+(4*2)+(3*9)+(2*6)+(1*4)=122
122 % 10 = 2
So 6729-64-2 is a valid CAS Registry Number.

The molecular addition of amphoteric molecules of organobismuth (III) compounds namely, o-tolylbismuth and p-tolylbismuth dihalides with nitrogen donor bidentate ligands 1, 10 phenanthroline and 2, 2′-bipyridine have been isolated and characterized by UV–

Synthesis, structure and reactions of μ- oxobis(arenesulfonatotriarylbismuth)

Sharutin,Egorova,Sharutina,Ivanenko,Pavlushkina,Gerasimenko,Pushilin

, p. 1359 - 1364 (2007/10/03)

Hydrolysis of triarylbismuth bis(arenesulfonates) in acetone gives bismuth derivatives of the general formula [Ar3Bi(OSO2Ar')] 2O (Ar = Ph, p-Tol; Ar' = Ph, C6H4Me-4, C 6H3Me2-2,4, C6H3Me 2-3,4). The structure of μ-oxobis[(3,4-dimethylbenzenesulfonato) triphenylbismuth] was established by means of X-ray diffraction. The molecule has a linear centrosymmetric structure with the bridging oxygen atom in the inversion center. The bismuth atom has a distorted trigonal bipyramidal coordination with the bridging oxygen atom and the arenesulfonate group in axial positions. The Bi-C and Bi-Oterm distances are 2.200(2), 2.204(3), and 2.442(2) A, and the Bi-Obr distances are 2.067(1) A. 2004 MAIK "Nauka/Interperiodica".
