Hydrolytic deallylation of N ‐allyl amides to give amides and propanal can be achieved with Pd II catalysts. The optimized catalyst consists of Pd(OCOCF 3 ) 2 and 1,3‐bis(diphenylphosphanyl)propane (DPPP). Several kinds of open‐chain N ‐allyl amides and N ‐allyl lactams undergo hydrolytic deallylation to give the corresponding amides and lactams in good to high yield. A mechanism which includes isomerization to enamides and subsequent hydrolysis is proposed. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
