《Unconventional Reactivity with DABCO-Bis(sulfur dioxide): C-H Bond Sulfenylation of Imidazopyridines》 was published in European Journal of Organic Chemistry in 2020. These research results belong to Le Bescont, Julie; Breton-Patient, Chloe; Piguel, Sandrine. Application In Synthesis of 1-Iodo-2-methoxybenzene The article mentions the following:
This work highlights the unexpected and unprecedented outcome of the reactivity with DABCO-bis(sulfur dioxide). The use of this reagent led to the exclusive introduction of a sulfur atom on the C-3 position of imidazopyridines instead of a sulfone group. The reaction methodol. turned out to be robust, scalable and suitable for various imidazopyridines and aryl iodides both bearing substituents with different electronic and steric properties (38 examples). Beyond the fact that this synthetic method complements the previously reported protocols for sulfenylation reactions, this work is meant to underline the unconventional role of DABCO-bis(sulfur dioxide). Thus, e.g., 2-phenylimidazo[1,2-a]pyridine + PhI + DABSO → I (68%) in presence of CuI/phenanthroline and tBuOK in DMF at 140°. A polemic in response to the work of D. Yang et al. (2018), who reported the preparation of sulfones under similar conditions. The results came from multiple reactions, including the reaction of 1-Iodo-2-methoxybenzene(cas: 529-28-2Application In Synthesis of 1-Iodo-2-methoxybenzene)
1-Iodo-2-methoxybenzene(cas: 529-28-2) participates in palladium catalyzed enantioselective Heck arylation of 2,3-dihydrofuran in the presence of chiral ionic liquids containing L-prolinate and L-lactate anions and non-chiral quaternary ammonium cations.Application In Synthesis of 1-Iodo-2-methoxybenzene
