Abstract
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 efficient preparation 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 with an alkenyl halide, and (iii) the cross- ...
