00925njm 22002777a 4500 dc Martínez Núñez, Clara author Velasco Pérez, Noelia author Sanz Díez, Roberto author Suárez Pantiga, Samuel author 2024-01 Conjugated 1-bromo or 1-iodo-1,3-dienes bearing a sulfide substituent have been synthesized via 1,2-sulfur migration from propargylic thioethers upon activation with NIS or NBS. The reaction generally proceeds with high control over the regio- and diastereoselectivity. Highly substituted thiophenes and selenophenes are easily obtained from the generated dienes. 1359-7345 http://hdl.handle.net/10259/10499 10.1039/D3CC06194A 1364-548X Synthesis of highly substituted 1,3-dienes through halonium promoted 1,2-sulfur migration of propargylic thioethers
