  日期：2003.4.1

  A highly regioselective radical addition of N,N-dichlorobenzenesulfonamide (dichloramine-B) to 1-alkenes is achieved at -78 degrees C by the use of triethylborane as a radical initiator. The reaction of 1,3-dienes with N,N-dichlorosulfonamide in the presence of Et(3)B regioselectively provides N-chloro-N-allylamide derivatives. N-chloro-N-allylamides thus obtained react with a variety of alkenes to
