NEW MATERIAL:A compound of formula I (group of formula II is one or two single bonds or one double bond; group of formula III is single or double bond; Z is H, O, ethyl, vinyl, ethylidene, OH or group containing ether bond; n is 1 or 2; R1 and R2 are H or CH3; A and B are H, CH3 or OH; at least one of A and B is OH). EXAMPLE:2-Methyl-5-(5- or 6-ethyl-2-norbornyl)-2-penten-1-ol. USE:A low-melting liquid, plasticizer, crosslinking agent, lubricant, perfume, synthetic intermediate, etc. PREPARATION:The compound of formula I can be produced by reducing a carbonyl-containing norbornyl derivative of formula IV (R3 is 3-6C aliphatic hydrocarbon group; R4 is H, CH3, C2H5, OH or alkoxy) such as 2-(4- carboethoxy-3-pentenyl)-5- or 6-ethylnorbornane with a reducing agent such as LiAlH4 in a solvent such as ether.
