Diethyl [(2-bromo-anilino)(1,3-diphenyl-1H-pyrazol-4-yl)meth-yl]phospho-nate
Abstract:
In the title compound, C(26)H(27)BrN(3)O(3)P, the central pyrazole ring forms a dihedral angle of 71.7 (2)° with the bromo-phenyl ring. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with R(2) (2)(10) ring motifs. Four C atoms of the 3-phenyl ring are disordered over two sets of sites [site occupancies = 0.745 (6) and 0.225 (6)].

Phosphodiester Linkages
Phosphodiester bond forms when a phosphoric acid molecule (H3PO4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function.
