Geschwindigkeitserhöhung durch Dispersionswechselwirkungen: Einfluss eines Hemicarceranden auf den Übergangszustand von Innerphasenzersetzungen von Diazirinen

Abstract: In memoriam Donald J. CramDas Konzept der molekularen Container und der Incarcerierung einzelner Molek¸le lieferte neue Ans‰tze f¸r die Behandlung wichtiger Themen aus Chemie und Biologie. [1] Dazu z‰hlen reaktive Intermediate, [2±5] Through-Space-Ph‰nomene, [6] Templatbildung, [7] Stereoisomerie [8] und Katalyse. [9] Dar¸ber hinaus gibt die Untersuchung von Innerphasenreaktionen Einblick in den Einfluss einer starren, elektronenreichen Umgebung auf den ‹bergangszustand einer Reaktion. [10] Dies ist besond… Show more

“…Molecular container compounds are hollow nanospheres that allow the encapsulation of one or more guest molecules and insulate them from the bulk phase 1–4. They have received much attention from the chemical community, in part owing to their potential application as nanoreactors in which otherwise fleeting reactive intermediates become persistent,5 reactions are accelerated,6–9 and regiochemistry and selectivity are altered 1011. The development of self‐assembly processes that involve hydrogen bonding and transition metal coordination chemistry has allowed the synthesis of nanometer‐sized capsules with remarkably high efficiencies 24.…”

“…However, this route to 15 ⋅guest is not applicable to thermally labile diazirines. The decay of some diazirines was even found to be accelerated by incarceration 10. Fortunately, 14 can be isolated as an intermediate en route to 15 .…”
