| | 2-METHYL-1,3-DITHIANE Usage And Synthesis |
| Uses | It has been employed in the synthesis of methyl ketones. 2-Methyl-1,3-dithiane is suitable for use in the preparation of potassium trifluoro(2-methyl-1,3-dithiano)borate. | | Synthesis Reference(s) | Tetrahedron Letters, 27, p. 6305, 1986 DOI: 10.1016/S0040-4039(00)87793-X | | General Description | 2-Methyl-1,3-dithiane is a versatile acyl anion equivalent. Role of hyperconjugation in the conformational analysis of 2-methyl-1,3-dithiane has been reported. | | Purification Methods | Wash the dithiane with H2O, 2.5 M aqueous NaOH, H2O, brine, dry over K2CO3 (use toluene as solvent if the volume of reagent is small), filter, evaporate and distil the colourless residue.
