The iodohydroxylation of 1,2‐allenyl sulfoxides with iodine in the presence of benzylthiol afforded 3‐hydroxy‐2‐iodo‐2(E)‐alkenyl sulfides in good yields and high regio‐ and stereoselectivities. In this reaction it was observed that the sulfoxide functionality was reduced to sulfide and the water in the reaction mixture plays an important role for the stereoselectivity observed. A mechanism involving

The selenohydroxylation of 1,2-allenyl sulfoxides with PhSeCl in MeCN/H2O (10/1) afforded E-3-hydroxy-2-phenylseleno-1-alkenyl sulfoxides in good yields and high regio-/stereoselectivities.
在MeCN / H 2 O(10/1)中用PhSeCl对1,2-烯基亚砜进行硒羟基化,可得到高收率和高区域/立体选择性的E -3-羟基-2-苯基硒基-1-烯基亚砜。
