An operationally simple, inexpensive, efficient, and environmentally friendly protocol for the amineexchangereactions of 3-N,N-dimethylaminopropiophenone and N,N-dimethylaminomethylferrocene with primary aryl amines is developed using the ionic liquid [bmim]PF 6 as a solvent. The recovered ionic liquid can be reused for several cycles with constant activity.

The hitherto unreported oxazastibinanes 3 have been synthesized by the sodium borohydride reduction of 3-phenyl-1-arylamino-3-oxopropane (1) and subsequent cyclization of the disodium salt of 3-phenyl-1-arylamino-3-hydroxypropane (2) with R3SbBr2 (R = Ph, p-tolyl, or mesityl). These compounds have been characterized by elemental analyses, molecular weight determination, and by IR, far IR, 1H, and 13C
