structural influences of THF on 1.LiI and 1.LiCN. For 1.LiI, small salt units are separated from the cuprate aggregate by THF. In contrast to this, THF disaggregates the oligomeric structures of 1.LiCN, while the core structures remain intact with salt attached. Thus, the reactivity of 1.LiI seems to be fine-tuned through distinct amounts of salt or THF, whereas the decreasing reactivity of 1.LiCN correlates
New oxygenated alicyclic derivatives useful as perfuming and odor modifying agents in the manufacture of perfumes or perfumed products, and as flavoring and taste-modifying agents in the aromatization of foodstuffs in general and imitation flavors for foodstuffs, beverages, animal feeds, pharmaceutical preparations and tobacco products. Novel processes for the preparation of said alicyclic derivatives and compositions of matter relating to mixtures containing same.
