Abstract

Transient organic silanones (CH3O) 2Si O (3) and (C6H5) 2Si O (4) were generated by vacuum pyrolysis from 3, 3-dimethoxy-6-oxa-3-silabicyclo [3.1. 0] hexane (6) and its 3, 3- diphenyl derivative (7), respectively, and after being trapped in argon cryogenic matrices at 12 K directly studied by IR spectroscopy. Vibrational assignments in the observed IR spectra of 3 and 4 have been made by comparison with the density functional theory B3LYP/6- ...
