General Description

2,2'-Bis(trifluoromethanesulfonyloxy)-1,1'-biphenyl, also known as BTB, is a chemical compound with the molecular formula C18H10F6O6S2. It is a white to off-white crystalline powder that is highly soluble in organic solvents. BTB is commonly used as a strong acid catalyst in various organic synthesis reactions, such as esterifications and acylations. It is also used as a precursor for the synthesis of other fluorinated compounds. Additionally, BTB has been studied for its potential applications in materials science, such as in the development of liquid crystals and organic electronic materials. Due to its high reactivity and strong acidity, proper precautions should be taken when handling and using BTB in laboratory settings.

A site-selective and stereospecific cascade Suzuki-Miyaura annulation of alkyl 1,2-bisboronic esters and 2,2′-dihalo 1,1′-biaryls

A cascade Suzuki-Miyaura cross-coupling giving rise to 9,10-dihydrophenanthrenes has been developed. Using biaryls with unsymmetrical substitution-pattern full site-selectivity was observed. Furthermore, this cross-coupling of an alkyl 1,2-bisboronic pinacol ester proceeds through the challenging coupling of a secondary boronate with complete stereoretention.

A Binaphthyl-Based Scaffold for a Chiral Dirhodium(II) Biscarboxylate Ligand with α-Quaternary Carbon Centers

A chiral dirhodium(II) paddlewheel complex has been synthesized from biscarboxylate ligands derived from BINOL, and the resulting complex has been used in enantioselective carbene/alkyne cascade reactions. The ligand design was guided by requirements of α

Efficient synthesis of biscarbazoles by palladium-catalyzed twofold C-N coupling and C-H activation reactions

A new and efficient strategy for the synthesis of 3,9′- and 2,9′-biscarbazoles was developed. Our strategy relies on the cyclization of 1,1′-biphenyl-2,2′-diyl bis(trifluoromethanesulfonate) with 4- or 3-anisidine, transformation of the methoxy to a triflate group and subsequent oxidative Pd-catalyzed cyclization with various anilines.
