DOI:10.1002/adsc.201300880
日期:2014.1.13
New reaction conditions for the rapid and productive intermolecularaminochlorination reaction of alkenes using a combination of chloramine‐T and a Brønstedt acid are described. Upon simple protonation of chloramine‐T, conditions for a mild and selective aminochlorination are obtained. In addition, the reaction can proceed to form either of the two possible regioisomers, depending on whether a stoichiometric

A potentmodular two-step approach to naphthyridine-based polyaromatic compounds was achieved through gold catalysis followed by acid-mediated condensation and in situ desulfonation. Besides the halochromic behaviour of all synthesised π-extended systems, one example shows outstanding sensitivity in detecting protons in non-protic solvents and allows a quantitative analysis in the low μm area.
