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-coupling of 2a and 2b with a series of arylhalides and triflate.
