摘要

氯代烷烃比碘化物/溴化化合物具有更丰富的结构和更低的成本，但由于其低还原电位和强键离解能，很少用作构建C（sp3）–C（sp三）键的亲电试剂。最近，一种涉及双核金配合物的新催化策略克服了这一限制。光诱导金催化模式引发了C（sp3）–Cl的亲电活化，导致氯代烷烃以氯烷基、烷基阳离子和碳链传播的卡宾当量前体的发散转化，并涉及双核金络合物催化剂与氯代烷烃之间的内球SET过程的新机制。

Excited-state gold catalyzed activation of inert C–Cl bonds

Chloroalkanes have richer structures and cheaper costs than iodide/brominated compounds, while rarely used as electrophilic reagents for constructing C(sp³)–C(sp³) bonds due to their low reduction potential and strong bond dissociation energy. Recently, a new catalytic strategy involving dinuclear gold complexes has overcome this limitation. The photoinduced gold-catalyzed mode initiated the C(sp³)–Cl electrophilic activation, lead to the divergent conversion of chloroalkanes as chloroalkyl, alkyl cation and carbene equivalent precursor of carbon chain propagation, and involved a novel mechanism of inner-sphere SET process between dinuclear gold complex catalyst and chloroalkane.

期刊介绍： Gold Bulletin is the premier international peer reviewed journal on the latest science, technology and applications of gold. It includes papers on the latest research advances, state-of-the-art reviews, conference reports, book reviews and highlights of patents and scientific literature. Gold Bulletin does not publish manuscripts covering the snthesis of Gold nanoparticles in the presence of plant extracts or other nature-derived extracts. Gold Bulletin has been published over 40 years as a multidisciplinary journal read by chemists, physicists, engineers, metallurgists, materials scientists, biotechnologists, surface scientists, and nanotechnologists amongst others, both within industry and academia. Gold Bulletin is published in Association with the World Gold Council.
