Triorganostannyl anions have proved to be excellent nucleophiles in S RN 1 reactions. 5 Application of these reactions to the synthesis of arylstannanes is currently in progress in our laboratory. We have recently described the photostimulated reactions of a number of haloarenes and haloheteroarenes with triphenylstannyl anions in dimethyl sulfoxide (DMSO) and acetonitrile (ACN) as solvents. 6 The photostimulated reactions of 1-chloronaphthalene, 2- and ...
