title: Mechanistic insights into the stepwise Diels-Alder reaction of 4,6-dinitrobenzofuroxan.
abstract: The stepwise Diels-Alder reaction between 1-trimethylsiloxy-1,3-butadiene and 4,6-dinitrobenzofuroxan is explored using state-of-the-art computational methods. The results support a stepwise mechanism via a persistent intermediate, however, not the one previously reported (Lakhdar et al., Chem. Eur. J.2007, 16, 5681) but a heterocyclic adduct. The novel DFT functional M062X and the SCS-MP2 method were essential to reproduce a reasonable potential energy surface for this challenging system.
