NEW MATERIAL:A compound of formula I (the bond containing dotted line is single or double bond; R1 is methyl, ethyl or vinyl; when R2 is H, R3 is (substituted) hydrocarbon group; when both R2 and R3 are hydrocarbon groups, terminals of said hydrocarbon groups may be bonded with methylene, methine, carbonyl or O to form a cyclic group; n is 0 or 1; when N is bonded through double bond, R2 is absent). EXAMPLE:(6-Vinyl-2-norbornyl)methylidene-O-carboethoxyaniline. USE:Perfume, plasticizer, crosslinking agent, rust-proofing agent, antioxidant or intermediate for organic syntheses. PREPARATION:The compound of formula I can be produced by reacting a norbornanone of formula II or norbornyl aldehyde of formula III with an amine in the presence of a mild acidic catalyst (e.g. sulfamic acid).
