3-Phenyl-2-tert-butyloxaziridine has been shown to behave as an oxidant under 800 MPa at 100 °C to oxidize sulfides to sulfoxides, in spite of having been reported to be inactive as an oxidant and to undergo thermal rearrangement to N-tert-butyl-α-phenylnitrone at atmospheric pressure. It has been shown that under thermal and high-pressure conditions the ability of the oxaziridine to react changes dramatically. The mechanism for the high-pressure reaction is also discussed.

The complex [PtMe2(bipy)] (1; bipy = 2,2′-bipyridine) fails to react with the oxaziridine derivatives RCHON-t-Bu (R = H, Ph, 2-pyridyl) in acetone at room temperature, but an easy reaction occurs in methanol solution to give the platinum(IV) complex [Pt(OH)(OMe)Me2(bipy)] and the corresponding imine RCH═N-t-Bu. In the case with R = Ph, the hemiaminal intermediate [Pt(OMe)(OCHPhNH-t-Bu)Me2(bipy)] was
络合物[PtMe 2(bipy)](1; bipy = 2,2'-联吡啶)在室温下无法与丙酮中的恶唑烷衍生物RCHON- t -Bu (R = H,Ph,2-吡啶基)反应,但是在甲醇溶液中容易发生反应,得到铂(IV)络合物[Pt(OH)(OMe)Me 2(bipy)]和相应的亚胺RCH═N- t -Bu 。在R = Ph的情况下,形成半胱氨酸中间体[Pt(OMe)(OCHPhNH- t -Bu )Me 2(bipy)],然后仅缓慢反应形成[Pt(OH)(OMe)Me 2(bipy) )]和PhCH═N- t -Bu 。计算研究表明1的反应与恶唑烷发生反应会产生电荷转移络合物,但进一步的反应需要氢键的协助和与特定甲醇分子的配位。这项工作为以下理论提供了有力的支持:氧原子从二恶英或恶二唑转移至1必须与质子转移耦合并且不涉及氧铂(IV)中间体。

a novel process of cycloaddition of C-aryloxaziridines with a variety of alkenes to afford stable, five-membered heterocycles 13–24. The steric hindrance of the tert-butyl group on the nitrogenatom of the oxaziridine is responsible for the high stereoselectivity of the cycloaddition reaction.
