Creger, Paul L. published the artcileMetalated carboxylic acids. III. Monoalkylation of alkylacetic acids. Possible alternative to the malonic ester synthesis for the preparation of dialkylacetic acids, Safety of 2-Butylhexanoic acid, the publication is Journal of the American Chemical Society (1970), 92(5), 1397-8, database is CAplus.
Alkanoic acids are converted to RCH2CO2-Na+, (R = cycloalkyl or C1-8 alkyl). The salts are treated with BuLi and and [RCHCO2]2- Li+ Na+ obtained are treated with BuBr, hexyl bromide, and n-octyl bromide to give RR1CHCO2H.
Journal of the American Chemical Society published new progress about 3115-28-4. 3115-28-4 belongs to catalysis-chemistry, auxiliary class Aliphatic Chain, name is 2-Butylhexanoic acid, and the molecular formula is C10H20O2, Safety of 2-Butylhexanoic acid.
