, xy, x refers to the imine starting material and y refers to the aryl introduced, pp.4-14
, Use of other hydride acceptors (acetone, (E)-1,4-diphenylbut-2-en-1,4dione or (E)-chalcone), catalysts (RuH2(CO)(PPh3)3 or RhCl(PPh3)3) or boron partners (PhBPin, PhB(OH)2, PhBF3K) only gave very sluggish reactions or afforded complex mixtures
, In a few cases, minor traces (~5%) of imine hydrolysis occurred during chromatographic purification
, All the C3-arylated imines were isolated by silica gel purifications. The aldehydes were obtained pure after the extraction step, except for rare cases (see SI)
