Vinyl sulfide formation with good yield and high regio- and stereoselectivities from thiols and acetylenes under transition-metal-free conditions is described. Potassium phosphate was used as an effective additive to enhance the reaction yield and selectivity. Z-Vinyl sulfides were predominately formed in the presence of potassium phosphate, whereas E-vinyl sulfides were formed under solvent- and base-free
描述了在无过渡金属条件下从硫醇和乙炔以高产率和高区域和立体选择性形成乙烯基硫化物。磷酸钾被用作有效的添加剂以提高反应产率和选择性。Z-乙烯基硫化物主要在磷酸钾存在下形成,而 E-乙烯基硫化物在无溶剂和无碱条件下形成。
