Nitroso compounds have emerged as highly valuable reaction partners or reagents in organic synthesis due to their rich reactivity. The versatile profile of these compounds allows them to function as electrophiles, nucleophiles, diradicals, and radical acceptors in diverse transformations. In recent years, notable progress has been made in harnessing photochemical reactions with nitroso compounds to prepare N,O-containing structures using mild and eco-friendly conditions. Various nitroso compounds like nitrosoarenes, acyloxy nitroso compounds, N-nitrosoamines and nitrites have received significant attention for their ability to introduce NO moieties into complex molecules that are otherwise difficult to access. In this review, we provide an overview of the recent advancements in the visible light-induced conversion of nitroso compounds, with particular emphasis on their role as bifunctional reagents and acceptors of radicals, carbenes and nitrenes.

亚硝基化合物由于其丰富的反应活性而成为有机合成中非常有价值的反应伙伴或试剂。这些化合物的多功能特性使它们能够在不同的转化中充当亲电子试剂、亲核试剂、双自由基和自由基受体。近年来，利用亚硝基化合物的光化学反应在温和且环境友好的条件下制备含N,O结构方面取得了显着进展。各种亚硝基化合物，如亚硝基芳烃、酰氧基亚硝基化合物、N-亚硝基胺和亚硝酸盐，因其能够将 NO 部分引入难以接近的复杂分子中而受到广泛关注。在这篇综述中，我们概述了可见光诱导亚硝基化合物转化的最新进展，特别强调了它们作为双功能试剂和自由基、卡宾和氮宾受体的作用。
