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 reaction between allyltrimethylsilane (1) and 4-phenyl-1,2,4-triazoline-3,5-dione (2) was studied, and the structures of three products were determined by using 1H NMR, 13C NMR, and mass spectra.The effects of solvent and temperature on the relative yields of products were studied, and a reaction mechanism involving an ionic intermediate was suggested.The mechanism of the reaction between diallyldimethylsilane (3) with triazolinediones was found to be quite similar to that of 1.
Ene Reaction of Triazolinediones with Alkenes. 1. Structure and Properties of Products
Ohashi, Shinichi,Leong, Koon-wah,Matyjaszewski, Kristoff,Butler, George B.
, p. 3467 - 3471 (2007/10/02)
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.
