Lewis Säure‐katalysierte Transferhydromethallylierung für den Aufbau quartärer Kohlenstoffzentren

Abstract: Das Design und die Synthese im Grammmaßstab eines cyclohexa-1,4-dienbasierten Surrogats fürI sobutengas wird beschrieben. Unter Verwendung der stark elektronenarmen Lewis-Säure B(C 6 F 5 ) 3 wurde die Hydromethallylierung elektronenreicher Styrolderivate zum Aufbau sterisch überfrachteter quartärer Kohlenstoffzentren erreicht. Die Reaktion verläuft unter C(sp 3 )-C(sp 3 )-Bindungsknüpfung an einem tertiären Carbeniumion, das selbst durch eine Alkenprotonierung erzeugt wird. Die Mçglichkeit zweier gleichzeitig … Show more

[36][37][38][39] The Oestreich group pioneered in the regioselective hydrodeuterogenation of 1,1-diarylalkenes in 2018 by using an unsymmetrical surrogate where the hydrogen and the deuterium atoms are bound differently, so that the hydrogen acts as a hydride equivalent (H + ) and the deuterium atom as a "heavy" proton (D À ).…”
