ABSTRACT
Several alcohols--interesting as cosmetic fragrances whose main preparative route on an industrial scale or in the research laboratory is the reduction of the corresponding carbonyl compound--were obtained by a solvent-free methodology in a green chemistry context. The process involves the simple mixing of the carbonyl compound with sodium borohydride dispersed in wet alumina in the solid state; the conversions of the carbonyl compounds were obtained in good yields within short reaction times, without energy consumption. The following carbinols were studied octan-3-ol, 2-cineolylols (endo-exo mixture), alpha-ionol, 4-methylbenzyl alcohol, 1-phenylethanol, trans-cinnamyl alcohol, p-anisyl alcohol, 4-phenyl-3-buten-2-ol.
