  Flash Pyrolysis of 1,1,1‐Trimethyltetrasilane ‐ Evidence for the Formation of Dibridged Si ₂ H ₂

  摘要：

  AbstractPulsed flash pyrolysis of 1,1,l‐trimethyltetrasilane (5) led to trimethylsilane, silane and a further species which is believed to be dibridged Si2H2 (13). Another route to 13 was found in the cocondensation of hydrogen and silicon atoms in an argon matrix at 12 K. The identification of matrix‐isolated 13 is based on observed IR bands at 1475.6, 1092.8 and 890.3 cm−1. These positions are in good agreement with the ab initio calculated wavenumbers for the strongest absorptions of 13. The band shifts for the mono‐ and dideuterated isotopomers support this assignment.
