Metal-free Reductive Coupling of Biphenyl Tosylhydrazones with Phenols or Benzyl Alcohols

摘要

Background: The 4-benzyl biphenyl scaffold represents an important structural element widely used in optoelectronic materials and bioactive compounds, including a variety of antihypertensive drugs and prostate cancer agents. Therefore, the construction of 4-benzyl groups incorporating this structural feature with cheap and readily available starting materials is of great scientific interest.
