A facile one-pot process for the formation of hindered tertiary amines.

Zhouyu Wang et al.

Molecules (Basel, Switzerland), 17(5), 5151-5163 (2012-05-05)

A simple and convenient method was developed for the preparation of hindered tertiary amines via direct reductive amination of ketones with secondary aryl amines, using trichlorosilane as reducing agent and tetramethylethylenediamine (TMEDA) as organic Lewis base activator. A broad range

Simultaneous determination of herbicide mefenacet and its metabolites residues in river water by solid phase extraction and rapid resolution liquid chromatography-mass spectrometry with pre-column derivatization.

Zhi-gang Yu et al.

Journal of chromatography. A, 1216(15), 3090-3097 (2009-02-19)

A procedure based on solid phase extraction (SPE) has been developed for the simultaneous pre-concentration of herbicide mefenacet (MN) and its three photolysis degradation products. Three metabolites studied were hydroxylbenzothiazole (HBT), N-methylaniline (N-MA) and 2-benzothiazoloxyacetic acid (2-BAA). A trimethylsilylation derivatization
