Vol. 60 acid chloride used while the secondary carbinol isolated accounted for 71% of the add chloride.All melting points are uncorrected.
Summary1. The reaction of ¿-butylmagnesium chloride with a large excess of pivalyl chloride at -10°g ives a 32% yield of hexamethylacetone and an 8% yield of neopentyl alcohol as its pivalic ester.2. The reaction of a large excess of ¿-butylmagnesium chloride at about 40°with pivalyl, isobutyryl and «-butyryl chlorides results, respectively, in a 1.5, 63 and 71% yield of addition and in a 94, 20 and 9% yield of reduction of the acid chloride to primary alcohol.
An apparatus for continuously recording the deposition or dissolution of radioactive material upon a radiationtransparent electrode during potential change is described.
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.
