| | 1-Tetralone Usage And Synthesis |
| Chemical Properties | Clear amber to brown oily liquid | | Uses | 1-Tetralone is a reagent used in the synthesis of amino-pyrazolopyridines with anti-NF-κB and pro-apoptotic potential. | | Synthesis Reference(s) | Tetrahedron Letters, 32, p. 4291, 1991 DOI: 10.1016/S0040-4039(00)92151-8 | | Purification Methods | Check the IR first. Purify α-tetralone by dissolving 20mL in Et2O (200mL), washing with H2O (100mL), 5% aqueous NaOH (100mL), H2O (100mL), 3% aqueous AcOH (100mL), 5% NaHCO3 (100mL) then H2O (100mL) and dry the ethereal layer over MgSO4. Filter, evaporate and fractionate the residue through a 6in Vigreux column (p 11) under reduced pressure to give a colourless oil (~17g) with b 90-91o/0.50.7mm. [Snyder & Werber Org Synth Coll Vol III 798 1955.] It has also been fractionated through a 0.5metre packed column with a heated jacket under reflux using a partial take-off head. It has max 247.5 and 290nm (hexane). The phenylhydrazone has m 83o. The 2,4,6-trinitrophenylhydrazone has m 247.5-248o (from EtOH).
