Les allylamines CH2 = CH - CD2NH2, = CD - CH2NH2, CH2 = CD - CD2NH2, ont ete preparees par reduction par AlLiH4 (ou D4), des adduits anthraceniques des acrylonitiles CH2 = CH - CN et CH2 = CD - CN. Pour les allylamines CD2 = CH - CH2NH2 et CD2 = CH - CD2NH2, deux methodes sont decrites: reduction soit de l'adduit anthrace;ne-acrylonitrile CD2 = CH-CN, soit de l'aduit anthracene-acrylamide CD2 = CH - CONH2. Les allylamines recuperees par decomposition de leurs adduits anthraceniques ont ete purifiees par chromatographie en phase vapeur et leur purete controlee par R.M.N. The allylamines CH2 = CH - CD2NH2, CH2 = CD - CH2NH2, CH2 = CD - CD2NH2, were prepared by reduction, by AlLiH4 (D4), of anthracene adducts of acrylonitriles CH2 = CH - CN and CH2 = CD - CN. For the allylamines CD2 = CH - CH2NH2 and CD2 = CH-CD2NH2, two methods are discussed: reduction either of the adduct anthracene - acrylonitrile CD2 = CH - CN, or of the adduct anthracene - acrylamide CD2 = CH - CONH2. The dideutered -3, 3 acrylonitrile and acrilyc acid were prepared by a Witting reaction. The allylamines were purified by G. L. C. and their purity were verified by N. M. R. spectroscopy. |
