Novel ruthenium-catalyzed vinylic substitution reactions of vinylic trifluoromethanesulfonates with nucleophiles such as cyclic 1,3-diketones and alcohols have been found to give the corresponding vinylic-substituted products in good to high yields. This catalytic reaction is considered to be a new type of vinylic substitution reaction. Reactions of α-ketoacetylenes with alcohols have also been found
已发现乙烯基三氟甲磺酸酯与亲核试剂(例如环状 1,3-二酮和醇)的新型钌催化乙烯基取代反应能够以良好到高产率得到相应的乙烯基取代产物。这种催化反应被认为是一种新型的乙烯基取代反应。还发现α-酮乙炔与醇的反应以良好的产率提供相应的乙烯基醚。这些催化反应可以通过提出钌-丁三叉基配合物作为关键中间体来进行解释。我们相信这一发现将开辟金属-枯草烯配合物化学的另一个方面。
