(formula presented) Allylic amines 5 are obtained in 30-55% overall yields by the base-catalyzed hydrolysis of trialkylated allylic urazoles 3; the latter are prepared by the TAD ene reaction of the appropriate olefin and further N-alkylation with α-bromo
Catalysis of Ene Reactions by Lithium Perchlorate
Davies, Alwyn G.,Kinart, Wojciech J.
, p. 2281 - 2284 (2007/10/02)
The ene reaction of some allylic hydrocarbons, and the metallo-ene reaction of some allyltin compounds, with 1,3,4-triazoline-2,5-diones or with diethyl azodicarboxylate as enophiles, in diethyl ether are strongly catalysed by lithium perchlorate.Azobenzene, on the other hand, reacts slowly with alkyltin compounds, undergoing hydrostannation.The reaction of cholesterol or of tributylallyltin with singlet oxygen is subject to a smaller catalysis.
Ene Reaction of Triazolinediones with Alkenes. 2. Kinetics and Substituent Effects
Ohashi, Shinichi,Butler, George B.

The kinetic measurements for the reaction of 4-substituted-1,2,4-triazoline-3,5-diones (4-R-TD; R=Ph, Me, p-MeOC6H4, p-NO2C6H4) with alkenes have been undertaken.The reactivity of alkenes was found to be very sensitive to substituent effects.The effects of solvent and substituent on TD were small.In the reaction of TD with ene products, side reactions as well as second-step ene reactions were observed.The reactions of 1-alkyl-4-phenyl-1,2,4-triazolidine-3,5-diones were investigated, and the reaction products were isolated.
