Kleine Ringe, 88. Reaktionen von Tetra‐tert‐butyltetrahedran: Oxidation zum Radikal‐Kation als einleitender Schritt

Small Rings, 88. – Reactions of Tetra-tert-butyltetrahedrane: Oxidation to the Radical Cation as the First Step The chemistry of tetrahedrane 1 and cyclobutadiene 3 is governed by the initial formation of radical cation 2. In spite of the high steric hindrance 2 cannot be isolated as a radical-ion pair. Reaction of 3 with O2 generates the oxete 21 which is surprisingly stable (up to 200°C).
