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.
