摘要: Abstract The gas phase pyrolysis (625°C, 10−2 mbar) of cyclopentadiene, dicyclopentadiene and trimethylsilylcyclopentadiene as well the monosilacyclobutanes Cp data (Cp=C5H5;R=Me, t-Bu, Cl) is described. In order to investigate reaction pathways copyrolysis Me2SiCH2CH2CH2 disilanes [Me3SiSiMe3, Me2ClSiSiClMe2, Me(Vi)SiSi(Vi)Me], respectively, with cyclopentadiene has been studied under same conditions. surprising formation aromatic systems benzene (main product) toluene interpreted on basis sequence intramolecular reactions silaethene intermediate Cp(R)SiCH2 (valence isomerisation, elimination).
