Hydrolytic deallylation of N-allyl amides to give amides and propanal can be achieved with PdII catalysts. The optimized catalyst consists of Pd(OCOCF3)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
使用 PdII 催化剂可以实现 N-烯丙基酰胺的水解去烯丙基化以得到酰胺和丙醛。优化后的催化剂由 Pd(OCOCF3)2 和 1,3-双(二苯基膦基)丙烷 (DPPP) 组成。几种开链N-烯丙基酰胺和N-烯丙基内酰胺进行水解脱烯酰化,以良好或高产率得到相应的酰胺和内酰胺。提出了一种包括异构化为烯酰胺和随后水解的机制。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
