Product 1

HCID 128530412-Fluoro-3'-methyl-1,1'-biphenyl

Procedure

A mixture of 5-(2-fluorophenyl)-3-methyl-2-cyclohexen-1-ol (16.6 g, 0.08 mole) and sulfur (7.8 g, 0.24 mole) was heated at 180°-230° for 7.5 hours. The reaction mixture then stood at room temperature for approximately 60 hours before it was distilled under reduced pressure to give 2'-fluoro-3-methyl[1,1'-biphenyl].
