A New Method for the Preparation of Aromatic Fluorine Compounds

Reprint of: Crystalline and liquid vapour pressures of the four p-monohalophenols: A thermodynamic study of their phase transitions

“…For p-fluorophenol, the temperature of the triple point is 0.2 K lower than the value of the temperature of fusion obtained through d.s.c. measurements and lies between the two literature available results [24,25]. Its enthalpy of fusion derived from the static vapour pressure results is close to the result derived from the DSC analysis.…”

Demonstration and analysis of bridging regioselectivity operative during di-.pi.-methane photorearrangement of ortho-substituted benzonorbornadienes and anti-7,8-benzotricyclo[4.2.2.02,5]deca-3,7,9-trienes

“…3-Iodoaniline (12). To a cooled (20 °C) stirred solution of stannous chloride dihydrate (854.5 g), methanol (1460 mL), and concentrated hydrochloric acid (965 mL) was added portionwise 229.0 g (0.920 mol) of 11. The mixture was stirred at ambient temperature for 8 h, freed of methanol by distillation below 45 °C at reduced pressure, and filtered to remove precipitated salts.…”
