Diborinic acid, B,B,B',B'-tetra-1-naphthalenyl-, also known as 1,1'-binaphthalene-2,2'-diylbis(boronic acid), is a complex organic compound with the molecular formula C26H20B2O4. It is a white crystalline solid that is soluble in common organic solvents such as dichloromethane, tetrahydrofuran, and toluene. Diborinic acid,B,B,B',B'-tetra-1-naphthalenyl- is a derivative of binaphthyl, which is a key structural motif in many chiral ligands and catalysts used in asymmetric synthesis. The presence of two boronic acid groups in the molecule allows it to act as a bidentate ligand, forming stable complexes with various metal ions. Diborinic acid, B,B,B',B'-tetra-1-naphthalenyl-, is widely used in the synthesis of chiral catalysts, particularly in the development of C2-symmetric ligands for transition metal-catalyzed reactions. Its unique structure and reactivity make it a valuable building block in the field of organometallic chemistry and homogeneous catalysis.
The CAS Registry Mumber 4426-20-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 6 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4426-20: (6*4)+(5*4)+(4*2)+(3*6)+(2*2)+(1*0)=74 74 % 10 = 4 So 4426-20-4 is a valid CAS Registry Number.
