Process for preparing 5-[1-(4-chlorophenyl)-methylene]-1-hydroxymethyl-2,2-dimethyl-cyclopentanol A process for preparing diols (Ia) and (Ib) by reacting an oxirane (II) with water and hydrogenating the resulting 5[1-(4-chlorophenyl)-meth-(E)-ylidene]-1-hydroxymethyl-2, 2-dimethyl-cyclopentanol (III) with hydrogen in the presence of a metal catalyst. Compounds (Ia), (Ib) and (III) are intermediates for synthesizing Metconazole. |
