Description

General description

Cyclobutyl methyl ketone (CMK, methyl cyclobutyl ketone) is an alicyclic ketone. It has been synthesized by reacting cyclobutanecarbonyl chloride with magnesium salt of malonic ester.[1] The mechanism of the photochemical reaction of gaseous mixtures of cyclobutyl methyl ketone diluted in argon has been studied by steady-state and pulsed (laser) photolysis.[2][3] It′s infrared (3500 to 30cm^-1) and Raman (3200 to 30cm^-1) spectra in gaseous and solid state has been recorded.[4] The UV spectra have been measured in alcohol and isooctane solution.[5] Study on the vapour phase thermal[6] and photodecomposition of methyl cyclobutyl ketone shows that the mode of decomposition is free radical in nature.[7]

Application

Cyclobutyl methyl ketone may be used as a model compound to study the oxidation mechanism of pinonic acid by hydroxyl radicals.[8][9]
