Tris(tetrahydrofuran-2-ylmethyl) borate, also known as THF-B, is a unique organoborate compound characterized by its three tetrahydrofuran-2-ylmethyl groups attached to a central boron atom. This chemical is known for its ability to act as a Lewis acid, which means it can accept electron pairs from other molecules, making it a useful catalyst in various organic reactions. Its cyclic structure and the presence of oxygen atoms in the tetrahydrofuran rings contribute to its stability and reactivity. THF-B is often employed in the synthesis of complex organic molecules, particularly in reactions that require the formation of carbon-carbon bonds, such as in the Suzuki-Miyaura cross-coupling reaction. Its solubility in organic solvents and its ability to form stable complexes with transition metals make it a valuable tool in modern organic chemistry.

6293-11-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6293-11-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,9 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6293-11:
(6*6)+(5*2)+(4*9)+(3*3)+(2*1)+(1*1)=94
94 % 10 = 4
So 6293-11-4 is a valid CAS Registry Number.

Copper-catalyzed trifluoromethylation of aryl iodides with potassium (trifluoromethyl)trimethoxyborate

Knauber, Thomas,Arikan, Fatih,Roeschenthaler, Gerd-Volker,Goossen, Lukas J.

scheme or table, p. 2689 - 2697 (2011/04/15)

Potassium (trifluoromethyl)trimethoxyborate is introduced as a new source of CF3 nucleophiles in copper-catalyzed trifluoromethylation reactions. The crystalline salt is stable on storage, easy to handle, and can be obtained in near-quantitative yields simply by mixing B(OMe)3, CF3SiMe3, and KF. The trifluoromethylation reagent allows the conversion of various aryl iodides into the corresponding benzotrifluorides in high yields under mild, base-free conditions in the presence of catalytic quantities of a CuI/1,10-phenanthroline complex.
