  • matrix isolation;
  • photoisomerizations;
  • cocondensation


Evaporation of silicon atoms and consecutive cocondensation with formaldehyde in an argon matrix was used to generate two CH2OSi isomers, namely silaoxiranylidene and silaketene. The latter can be considered as a complex of carbon monoxide and silylene rather than as a true (planar) ketene. Structural assignments for the observed species are carried out by comparison of experimental and calculated IR spectra and thus are a good example for the combination of quantum chemical calculations and experimental work. Theoretical aspects of the CH2OSi energy hypersurface as well as the photochemistry of the observed silaketene are compared with earlier results.
