Represented herein is a simple thiol identified as an effective precursor to photochemically form a carbocation. Thanks to the thiyl radical rapid transformation to disulfide, which serves not only to stabilize the generated thiyl radical but also to allow the second electron transfer to form a carbocation. The resulting carbocations, including primary benzylic, secondary, and tertiary carbocations
本文代表的是一种简单的硫醇,被鉴定为光化学形成碳正离子的有效前体。由于硫基自由基快速转化为二硫化物,这不仅可以稳定生成的硫基自由基,还可以允许第二次电子转移形成碳正离子。所得的碳正离子,包括伯苄基碳正离子、仲碳正离子和叔碳正离子,可以与氮、氧和碳亲核偶联伴侣以及复杂的药物分子顺利偶联,同时在空气中形成元素硫。
