Diels-Alder reactions of 1,1-dimethyl-2,3,4,5-tetraphenyl-1-silacyclopentadiene, 1,1-dimethyl-2,5-diphenyl-1-silacyclopentadiene and 1,1-dimethyl-3,4-diphenyl-2-silacyclopentadiene with maleic anhydride have been carried out.The rates of these second order reactions have been measured by 1H FT NMR over a range of temperatures.Arrhenius plots of these data yield the activation parameters for these reactions.The synthesis of 1,1-dimethyl-3,4-diphenyl-1-silacyclopentadiene is reported.
