We have developed shelf- and air-stable ortho-stannylated aniline reagents that can directly be coupled with alkenyl and aryl halides via Migita–Kosugi–Stille cross-coupling. We report (i) the efficientpreparation of o-(tributylstannyl)aniline (2a) and o-(trimethylstannyl)aniline (2b), (ii) the comparison of the reactivities of 2a and 2b with those of related organostannanes in cross-coupling reaction
