在过去的十年里,受挫折的刘易斯对(FLP)化学的反应性和应用出现了爆炸性的增长。尽管如此,这些转化中的刘易斯酸(LA)通常是硼烷,而较重的p-区元素令人惊讶地很少受到关注。新的LA Bn3SnOTf(1)已从简单,廉价的起始原料合成,并已进行光谱和结构表征。与先前报道的R3SnOTf LAs相比,锡中心电子的微妙调制导致其刘易斯酸性增加,并且促进了低温氢活化和亚胺氢化。还研究了R3Sn + LA核的失活途径。本文是主题问题“沮丧的刘易斯配对化学”的一部分。
Over the last decade there has been an explosion in the reactivity and applications of frustrated Lewis pair (FLP) chemistry. Despite this, the Lewis acids (LAs) in these transformations are often boranes, with heavier p-block elements receiving surprisingly little attention. The novel LA Bn3SnOTf (1) has been synthesized from simple, inexpensive starting materials and has been spectroscopically and structurally characterized. Subtle modulation of the electronics at the tin centre has led to an increase in its Lewis acidity in comparison with previously reported R3SnOTf LAs, and has facilitated low temperature hydrogen activation and imine hydrogenation. Deactivation pathways of the R3Sn+ LA core have also been investigated. This article is part of the themed issue ‘Frustrated Lewis pair chemistry’.
