1,2,3-Triphenyl-2-phospha-bicyclo[3.1.0]hex-3-ene 2-oxide is a complex organophosphorus compound characterized by a unique bicyclic structure. It features a phosphorus atom at the center, bonded to three phenyl rings and a bicyclic hexene ring system. The 2-oxide functional group is present, indicating an oxygen atom double-bonded to the phosphorus, which influences the compound's reactivity and stability. This molecule is of interest in the field of organophosphorus chemistry, potentially for its applications in materials science, as a ligand in coordination chemistry, or as a precursor in the synthesis of more complex phosphorus-containing molecules. Its specific properties, such as electronic behavior and steric effects, arise from the interplay between the phosphorus center and the surrounding aromatic and cyclic frameworks.
The CAS Registry Mumber 1474-99-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,7 and 4 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1474-99: (6*1)+(5*4)+(4*7)+(3*4)+(2*9)+(1*9)=93 93 % 10 = 3 So 1474-99-3 is a valid CAS Registry Number.
