Cascade carbopalladation nitrogen nucleophiles

There are hardly any examples for the use of sulfur nucleophiles in terminating cascade carbopalladation sequences, in contrast to oxygen and especially nitrogen nucleophiles. One reason for this might be found in the problems associated with the high degree of coordination of the palladium with the less oxidized sulfur nucleophiles such as thiols. However, arylsulfinates are excellent nucleophiles for cascade termination reactions, as has been shown by Grigg et al. (Scheme 34). ...
