Photoinduced heterodisulfide metathesis for reagent-free synthesis of polymer nanoparticles

Reagent-free synthetic methods are of great interest because of their simplicity and implications in green chemistry. We have taken advantage of photoinduced heterodisulfide metathesis to generate crosslinked polymer nanoparticles. The method of development and the mechanistic basis for the synthetic approach are outlined in this communication.

Gas-phase pyrolytic reactions of esters of 2-pyridine and 8-quinoline sulfonic acid

The rates of gas-phase thermal elimination reaction of esters of 2-pyridine sulfonic acid and 8-quinoline sulfonic acid have been measured over at least 50° for each compound. The relative rates of the first-order unimolecular decomposition at 500 K for the primary:secondary esters suggest that C-O bond breaking is kinetically more significant than C-H bond breaking, leading to a transition state of carbocationic character. This is consistent with the electron-donating effect provided by the methoxy substituent in 2-p-methoxyphenylethyl of 2-pyridine and 8-quinoline sulfonate esters stabilizing the carbocation center.
