are obtained by reaction of AlH3 with pyrrolidine enamines of acyclic and cyclic ketones. Enamines of α-substituted cyclohexanones are converted to 3-alkylcyclohexenes. Those derived from disubstituted acetaldehydes are only poorly hydrogenolysed as is the dienamine derived from Δ1,9-octalone. 1-N-Pyrrolidinocyclo-octene is unique in giving cyclo-octane in the hydrogenolysis reaction; trans-cyclo-octene
烯胺与AlH 3,AlH 2 Cl和AlHCl 2反应,分别得到饱和胺和烯烃,分别是氢化和氢解的产物。后者的比例与氯化还原剂相比较低。通过使AlH 3与无环和环状酮的吡咯烷烯胺反应,可获得良好的烯烃收率。α-取代的环己酮的烯胺被转化为3-烷基环己烯。那些从二取代乙醛衍生仅氢解很差如从Δ得到的氨醇二烯胺1,9- -octalone。1-N-吡咯烷基环辛烯在氢解反应中产生环辛烷的独特之处。反式-环辛烯是可能的中间体。
