Abstract
The acid-catalysed decompositions of 3-diazobutan-2-one and of ethyl diazopropionate show general acid catalysis. Data are reported for both compounds for a series of carboxylic acids and for H3O+ as catalysts. The Brønsted coefficient is 0·61 for 3-diazobutane-2-one and 0·59 for ethyl diazopropionate. The difference in the u.v. spectra between diazo-ketones and diazo-esters is also discussed.Keywords
