The carbonylation and cyclization of N-alkylallylamines to y-butyrolactams is efficiently achieved by use of RhCI, 3H20/PPh, or RhCl(COXPPh,), as catalyst precursors under mild conditions (7O"C, 10 bar) when CO/H, (4: 1) mixtures are used instead of pure CO. Mechanistic studies on the Rh and the ana
