6-Lutidine has been identified as a beneficial additive for the oxidative cleavage of olefins to ketones by NaIO4 in the presence of catalytic RuCl3, improving the yield and shortening the reaction times. In the absence of 2,6-lutidine reactions stalled at the diol intermediate with incomplete conversion to the desired ketones. The reaction protocol described herein also avoids the use of harmful solvents
2,6-尿苷已被确认为在催化RuCl 3存在下NaIO 4将烯烃氧化裂解为酮的有益添加剂,从而提高了收率并缩短了反应时间。在不存在2,6-二甲基吡啶的情况下,反应停在二醇中间体上,不完全转化为所需的酮。本文所述的反应方案还避免了使用有害溶剂,例如CCl 4和DCE,并且耐受一定范围的官能团。
