Only meager knowledge exists concerning alkyl1 fluorides, in contrast to the extensive literature relative to the other halogen alkyls. Until recently the methods of preparation for alkyl fluorides were cumbersome, and larger quantities of them were available only with difficulty. The ease of decomposition of the tertiary and secondary alkyl fluorides, particularly in the presence of impurities, added another determent to their accurate investigation.Our new method of their preparation (23, 24)-namely, the addition of hydrogen fluoride to olefins and the splitting of cyclopropane (or its alkyl derivatives) with hydrogen fluoride-makes them readily available in large quantities. It permitted us to complete their study, which was pioneered by the investigations of Dumas (19), Fremy (21), Moissan (38, 37), Meslans (38,33,34,35,36) and in more recent years by F.
