The compounds Ph3MCH2CH=CH2 and (M=Si, Ge, Sn or Pb) have been treated with 4-phenyl-1,2,4-triazoline-3,5-dione, and the relative yields of the products of the M-ene reaction, of the H-ene reaction, and of the reaction involving cycloaddition with shift of the organometallic substituent, have been determined.The silicon compounds react principally by the H-ene process.The cycloaddition process is at a maximum (50percent or 70percent) with the germanium compounds, and the tin compounds show mainly the M-ene reaction, with some cycloaddition but no H-ene reaction.Triphenylprop-2-enylplumbane show only the M-ene reaction.In trimethyl(1,1-dimethylprop-2-enyl)silane, in which the H-ene reaction is blocked, only cycloaddition with shift of the silyl group is observed.

Allylic tin compounds (I) react with singlet oxygen to give allylperoxystannyl compounds (II) by stannylallylation, stannylallyl hydroperoxides (III) by hydroallylation, and 4-stannyl-1,2-dioxolanes (IV) by rearrangement and cycloaddition.For example, 3-t

The structures of ene products from reaction of triazolinediones with alkenes and polyisoprene were studied by using (1)H NMR.The pKa values of the ene products were measured.The reactivity and stability of the ene products were also studied.

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.
