The isocyanates of silicon (CH3)2Si(NCO)2 and Si(NCO)4 react with CH3N[Sn(CH3)3]2 and N[Sn(CH3)3]3 to yield the cyclic derivatives 2a-2b as well as the spiro compound 3. The structures of the compounds are discussed on the basis of 1H NMR and IR data. Mass spectra are not conclusive for assigning a certain structure. SO2(NCO)2 and (CH3)3Si-S-Si(CH3)3 form a cyclic compound 4 which contains two sulfur atoms of coordination number two and four. The results of the mass spectra can be interpreted by assuming that a rearrangement occurred. 4 hydrolyses under formation of 5.

Vacuum ultraviolet single-photon ionization time-of-flight mass spectrometry (VUV-SPI-TOFMS) has been applied to the detection of volatile organic compounds (VOCs), including aromatic, chlorinated, and oxygenated compounds. Photoionization mass spectra of 23 VOCs were measured using SPI-TOFMS at 10.5 eV (118 nm). The limits of detection of VOCs using SPI-TOFMS at 10.5 eV were estimated to be a few ppbv. The mass spectra of 20 VOCs exhibit only the parent ion and its isotopes' signals. The ionization processes of the VOCs were discussed on the basis of the reaction enthalpies predicted by the quantum chemical calculations. Absolute photoionization cross-sections for 23 VOCs, including 12 newly measured VOCs, at 10.5 eV were determined in comparison to the reported absolute photoionization cross-section of NO.
