The recent preparation and isolation of -furfuryl chloride1 has greatly simplified the synthesis of -furfuryl compounds and it is now possible, by using this reagent, to prepare compounds which were in many cases previously obtainable only by more or less indirect methods which usually started with furfural and involved several steps in the procedure. By the use of -furfuryl chloride, which contains a highly reactive chlorine atom, we have prepared the following new compounds, which are listed in Table I, together with their physical constants.

Chloral either alone or, better, in the presence of a trace of hydrogen chloride, combines with acetaldehyde,17 propionaldehyde, wobutyraldehyde and trimethylacetaldehyde to give paraldehydes corresponding to the general type (2RCHO + CCl3CHO).2. It apparently does not combine with acetaldol under similar conditions.3. Attempts to prepare a mixed paraldehyde containing three different aldehydes were unsuccessful.4. The possible role played by such derivatives in plant and animal life would seem to call for some consideration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
