Abstract:
Simple methods for producing 3,7-dimethyl-5,7-octadiene-1-ol and rose oxide are disclosed. Each of the methods comprises only one step in which the raw material, 3,7-dimethyl-6-hydroxy-7-octene-1-ol is dehydrated or further cyclized by heating while stirring at 80 to 160 DEG C in the presence of a zero-valent or divalent phosphine-palladium complex, or a combination of zero-valent or divalent palladium and a phosphorous compound having coordinating capabilities such as the combination of palladium acetate and triphenylphosphine. The methods give high yields and have cost saving characteristics.
