A transition-metal-free protocol for the synthesis of non-terminal alkenyl ethers, alkenyl sulfides, and N-vinylazoles from arylaldehydes or diarylketones, DMSO and O, S, N-nucleophiles has been reported. In this protocol, 24 examples of non-terminal alkenyl ethers and 28 examples of non-terminal alkenyl sulfides in 72–95% yields have been synthesized within 5 min. Moreover, 27 examples of non-terminal
已经报道了一种从芳醛或二芳基酮、DMSO 和 O、S、N-亲核试剂合成非末端烯基醚、烯基硫化物和 N-乙烯基唑的无过渡金属方案。在该协议中,在 5 分钟内合成了 24 个非末端烯基醚的例子和 28 个非末端烯基硫化物的例子,产率为 72-95%。此外,在 2 小时内还合成了 27 个非末端 N-乙烯基唑的例子,产率为 57-88%。初步机理研究表明,芳醛或二芳基酮提供了一个碳原子,DMSO提供了一个次甲基,O,S,N-亲核试剂贡献了一个X原子来构建C=C-X结构。
