Abstract:
The title compound, C(45)H(27)P, was obtained as a product of the reaction of triphenyl-methyl-enephospho-rane with one molar equivalent of 1,4-diphenyl-butadiyne in toluene. The compound was very stable under ambient conditions, but rapidly decomposed in solution when exposed to the air. The P atom is tetra-coordinated in an approximately tetrahedral geometry. The length of the C C triple bond [1.206 (2) Å] is in the normal range.

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.
Phosphodiester Bonds Link Nucleotides Together
DNA and RNA are polynucleotides or long chains of nucleotides that are linked together. A nucleotide is...
