NS-containing ligands with the 2-thioaniline motif and imine functional group linked phenyl, 2-pyridyl and 2-thienyl pendants were synthesized by imine condensation reactions with corresponding aldehydes. 2-(methylthio)-N-(2-thienylmethylene)-benzenamine is a new compound characterized by NMR, FTIR and UV–vis. Single crystal X-ray crystallographic data was obtained for all three ligands. The corresponding...
The first use of diazaphospholenes as chiral catalysts has been demonstrated with enantioselective imine hydroboration. A chiral diazaphospholene prepared in a simple three‐step synthesis from commercial materials has been shown to achieve the highest enantioselectivity for the hydroboration of alkyl imines with pinacolborane reported to date. Enantiomer ratios of up to 88:12 were obtained with low...
