The thermal treatment of 4-homoadamantanol and bicyclo [3.3. 1] nonanols with hexamethylphosphoric triamide (HMPT) gave the corresponding olefins in moderate yields. The application of this dehydration method to a system in which olefin formation was regarded as difficult or impossible stereochemically led to various types of reactions, ie, reduction, substitution, and phosphorodiamidation. Upon being heated in HMPT, 2- ...
