The reactions of oxygen atoms and substituted methylsilanes have been investigated in argon matrices at 14-17 K.Products were identified by using isotopic 18O3 precursor and deuterium substitution in the Si-H bonds.With MeSi3, Me2SiH2, and Si2H6, the silanols MeSiH2OH, Me2SiHOH, and SiH3SiH2OH were formed, respectively.These molecules contain the Si-O-H functional group with 3708-3711 cm-1 O-H stretching frequencies.For Me4Si, the carbinol Me3SiCH2OH was produced with a lower 3637 cm-1 O-H stretching frequency.Me3SiH was different: the silanol was not observed, but instead a product tentatively identified as CH2=Si(OH)Me was formed.Also, the silanones H2SiO and Me(H)SiO were produced from MeSiH3, Me(H)SiO and Me2SiO were formed with Me2SiH2, and Me2SiO was again observed with Me3SiH.These silanones contain the Si=O functional group with stretching frequencies of 1201-1209 cm-1.
