Ozonolysis of olefins Ia-c containing a cyclopropylidene group, does not follow the classical Criegee mechanism but gives the anomalous products IIa-c, IIIa-c,IVa-c and Va-c, as outlined in Scheme 2. None of these oxidation products contains the cyclopropyl ring any more. It is suggested ...

Cyclic alkenes are converted into linear products; molecules with multiple alkenes are converted into a mixture of fragments More electron-rich (i.e. more substituted) alkenes tend to react faster Alkynes can also undergo oxidative cleavage with O3, giving carboxylic acids. Alkynes are less reactive...

Synthesis of novel fused β-lactams by intramolecular 1,3-dipolar cycloadditions. Part 9. Preparation of the 7-oxo-1,3-diazabicyclo[3.2.0]- heptane-2-carboxylate and 8-oxo-1,3-diazabicyclo[4.2.0]octane-2-carboxylate ring systems 4-Vinylazetidin-2-one (24) has been converted into 1-...
The impact of each pretreatment stage on the physical structure of the SCB was evaluated by its chemical composition, using an infrared technique (FTIR-ATR), and using thermogravimetric analysis (TGA/DTG). The pretreatment sequence O, B, U provided a significant reduction of lignin and ...
Product ion signals were simultaneously observed by the NH4+-CI3-TOF and the acetate chemical ionization atmospheric pressure interface time of flight mass spectrometer (acetate-CI-API-TOF). Both instruments are in remarkable good agreement within a factor of two for HOMs. For OMs not containing ...
