2-METHYL-1,3-DITHIANE Usage And Synthesis
UsesIt 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 Description2-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 MethodsWash 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.
