- Unprecedented 1,4-stannatropy: Effective generation of azomethine ylides as nitrile ylide equivalents from N-(stannylmethyl)thioamides
-
Generation and cycloaddition of less- or non-stabilized azomethine ylides, or nitrile ylide equivalents, via unprecedented 1,4-stannatropy of N-(tributylstannylmethyl)thioamides were achieved. The reactions with dipolarophiles, such as electron-deficient alkenes and alkynes, afforded corresponding pyrrolidine and pyrrole derivatives effectively. The Royal Society of Chemistry 2006.

- Gas- Phase Ion Chemistry of Siloxide and Silamide Ions by Using the Flowing Afterglow. Unusual Rearrangements Involving SiO and SiS Bond Formation
-
Siloxide ions undergo O/S exchange reactions with suitable sulfur-containing neutrals, e.g.H3SiO- + CS2 -> H3SiS- + COS.Silamide ions similarly undergo NR/O and NR/S exchange reactions together with nucleophilic displacement reactions, e.g.: .No simple correlation between rate and mechanism is observed for all the studied reactions.

- Gas-phase Thermolyses. Part 3. Gas-phase Thermolysis of Silylated Thionocarboxylic Acid Derivatives: a Route to Thioketens?
-
The unimolecular gas-phase thermolytic decomposition of three silylated thionocarboxylic acid derivatives (2b), (3), and (8) have been studied by the flash vacuum thermolysis-field ionization mass spectrometry technique in the temperature range from 783 to 1404 K in order to elucidate its possible applicability as a route to thioketens.Only very minor amounts of the expected thioketens were found, whereas the corresponding ketens were obtained as the major products.A possible mechanism for keten formation is discussed.
