A method for the synthesis of vinyl derivatives of the terpenols verbenol and fenchol by their reaction with calcium carbide was developed. It was found that addition of potassium fluoride affects the yield of nucleophilic addition of the corresponding alcoholate ions to acetylene.

Lithium perchlorate suspended in dichloromethane is an efficient catalyst (4 – 25 mol-%) for stereoselective Diels-Alder, hetero-Diels-Alder and regioselective 1,3-Claisen rearrangements; this process is milder, safer and environmentally less precarious than the use of 1 – 5 molar solution of LiClO4 in ether described previously in the literature.
