一般說明

5-Methyl-2-hexanone (methyl isoamyl ketone, MIAK) is an aliphatic ketone. Its ability to elicit germination response in uredospores of certain species of rust has been investigated. The near-UV absorption cross section and absorption spectrum of MIAK were measured and employed to determine its photolysis lifetime. The dynamics of the Norrish Type-II reaction of MIAK has been studied using femtosecond time-resolved mass spectrometry.

應用

5-Methyl-2-hexanone may be used to synthesize N,N′-bis(1,4-dimethylpentyl)-p-phenylenediamine (BMPPD) via reductive alkylation of p-nitroaniline in the presence of copper-based catalysts.
