A novel, convenient and chemoselectiveprocedure for oxidizing sulfides to sulfoxides with 30% aqueous H 2 O 2 in phenol at room temperature is described. The procedure is very simple and no strict conditions were requiredfor the selective conversion without affecting the functional groups even including the highly reactive aldehyde group. The reactions proceeded very quickly in excellent yields. Some
描述了一种在室温下用苯酚中的 30% H 2 O 2 水溶液将硫化物氧化为亚砜的新颖、方便和化学选择性的方法。该过程非常简单,选择性转化不需要严格的条件,而不影响官能团,甚至包括高反应性醛基。反应以极好的收率进行得非常快。提出了一些描述溶剂作用的实验证据。

N-Bromosuccinimide efficiently catalyzes the hydroamination and hydroalkoxylation of activated styrenes using tosylamides, carbamates, and alcohols as the nucleophiles to afford amino and ether derivatives, respectively. Both the processes give good to excellent yields of the products with 100% regioselectivity (Markovnikov fashion).
