N,N-bis(trimethylsilyl)alkenesulfenamides: synthesis and transaminations via S-alkenylthiophthalimides. A general route to alkenesulfenamides and alkenesulfonamides
Abstract
N,N-bis(Trimethylsilyl)alkenesulfenamides 3, prepared by the reaction of trans-alkenesulfenates with TMSCI and LiHMDS, are modified to their corresponding S-alkenylthiophthalimides 6 which are then converted to alkenesulfenamides 7 bearing more general nitrogen functionality.
