Tris(m-methoxyphenyl) borate, also known as TMP borate, is an organoborane compound with the chemical formula C18H21BO3. It is a colorless, crystalline solid that is soluble in organic solvents. TMP borate is widely used as a Lewis acid catalyst in various organic reactions, such as esterification, transesterification, and Friedel-Crafts alkylation. It is also employed as a flame retardant and a stabilizer for polymers. Due to its high thermal stability and low toxicity, TMP borate has gained significant attention in the chemical industry for its potential applications in various fields.

Check Digit Verification of cas no

The CAS Registry Mumber 42080-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,8 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 42080-76:
(7*4)+(6*2)+(5*0)+(4*8)+(3*0)+(2*7)+(1*6)=92
92 % 10 = 2
So 42080-76-2 is a valid CAS Registry Number.

A new regio- and stereoselective intermolecular Friedel-Crafts alkylation of phenolic substrates with aryl epoxides

Bertolini, Ferruccio,Crotti, Paolo,Macchia, Franco,Pineschi, Mauro

, p. 61 - 64 (2006)

A conceptually new regioselective and highly syn-stereoselective intermolecular Friedel-Crafts-type O-alkylation of phenols with aryl epoxides by the use of appropriately substituted aryl borates is reported. The carbon-carbon bond formation occurs in neutral and mild conditions without the need for external Lewis acids or transition metal catalysts.
