Abstract
Abstract We describe a specific procedure for the synthesis of deuterium-labelled 2-(1-methylalkyl)succinate established via alkylation of diethyl malonate, Krapcho decarboxylation reaction with D 2 O and hydrolysis reaction. Two novel compounds, 2-[ 2 H ]-2-ethylsuccinic acid and 2-[ 2 H ]-2-(1-methylheptyl)succinic acid were prepared via this synthetic route and characterized by mass spectrometry and 1 H NMR. The results showed that the 2-(1-methylalkyl)succinic acids were deuterated at the β -position, which is considered as an important reaction centre in the anaerobic degradation of n -alkanes.
