A mild and efficient procedure for the protection of carbonyl compounds as 1,5-dihydro-3H-2,4-benzodioxepines in high yields is described by using a readily available and inexpensive KSF clay catalyst.
Sulfonated charcoal, a mild and efficient reagent for the preparation of cyclic acetals, dithioacetals and benzodioxepines
Patney, Haris K.
, p. 413 - 416 (2007/10/02)
1,3-Dioxolanes, 1,3-Ditholanes and 1,5-dihydro-3H-2,4-benzodioxepines were prepared by the direct condensation of carbonyl compounds with 1,2-ethanediol, 1,2-ethanedithiol or 1,2-benzenedimethanol under the heterogeneous conditions of sulfonated charcoal catalyst.
