  Two star-shaped structures of the his- and tris-thiophene methane types have been synthesized in a facile two-step synthesis. The resulting his- and tris-thiophene methanes readily react with oxygen both as solids and in solution to yield stable radicals. The formed radicals, which were investigated using electron paramagnetic resonance (EPR), were found to be residing on the central carbons of the his- and tris-thiophene methanes.

  I dette innlegget vil jeg fokusere på bruken av animasjon som hjelpemiddel til å levendegjøre organisk kjemi. I dag kommer de fleste lærebøker i kjemi med CDer som på ulike vis bidrar til å gjøre det lettere for studentene å tilegne seg stoffet. Flere av CDene inneholder animasjoner av høy kvalitet. Dessuten finnes det gode animasjoner i kommersielle kjemiprogram som kan benyttes som supplement til forelesninger. Jeg vil vise eksempler på animasjoner hentet fra følgende kilder: 1. John McMurry: Organic Chemistry Online (CD) 2. T. S. Solomon: Organic Chemistry (CD) 1. Exeter Multimedia Publishing: ChemTV 2. Falcon Software: Organic Reaction Mechanism 3. ChemLibris: Molecular Movies Deler av dette benyttes i undervisningen i organisk kjemi ved Universitetet i Oslo i kursene KJ120 og KJ222 (Organisk kjemi I og II).
