Abstract

An open-chain iron pyridine-NHC framework is expanded utilizing a benzimidazole moiety. The new iron(II) NHC complex is characterized and employed in olefin epoxidation. It is remarkably temperature tolerant and achieves a TOF of ca. 10 000 h⁻¹ and TON of ca. 700 at 60 °C with Sc(OTf)₃ as additive.

配体设计对铁 NHC 环氧化催化剂的影响

利用苯并咪唑分子扩展了一种开链铁吡啶-NHC 框架。这种新的铁(II) NHC 复合物的特点是可用于烯烃环氧化反应。它具有显著的耐温性，在以 Sc(OTf)3 为添加剂的 60 °C 条件下，TOF 约为 10 000 h-1，TON 约为 700。

期刊介绍： ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
