Tris-(β-phenylethyl)telluronium chloride, also known as TPBTC, is a chemical compound with the formula C18H19ClTe. It is a white crystalline solid that is soluble in organic solvents. TPBTC is a versatile reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and carbon-heteroatom bonds. It acts as a Lewis acid catalyst, promoting various reactions such as Friedel-Crafts alkylation, cyclization, and cross-coupling reactions. The compound is also known for its ability to activate simple arenes and heteroarenes, making it a valuable tool in the synthesis of complex organic molecules. TPBTC is recognized for its stability, ease of handling, and low toxicity, which makes it a preferred choice over other more hazardous reagents in certain chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 75529-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,2 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75529-07:
(7*7)+(6*5)+(5*5)+(4*2)+(3*9)+(2*0)+(1*7)=146
146 % 10 = 6
So 75529-07-6 is a valid CAS Registry Number.

Mechanism of Thermal Decomposition of Tetra-aryltellurium Species

Glover, Stephen A.

, p. 1338 - 1344 (2007/10/02)

Tetra-aryltellurium species decompose upon heating giving good yields of diaryl tellurides and biphenyls.Radical-scavenging experiments show that phenyl radicals are not intermediates in the formation of biphenyls.In contrast, cross-over experiments give mixed biphenyls as well as mixed diaryl tellurides, but these are formed by a statistical redistribution of organic groups giving mixed tetra-aryltellurium species which decompose thermally in an indiscrimate fashion.
