(SnMe3)2 with aryl triazene offers a new strategy
for the synthesis of aryl stannane. A variety of synthetically useful
aryl trimethylstannanes were produced in moderate to good yields with
this metal-free approach. One-pot sequential Stille cross-coupling
with different aryl bromides provides a short entry to both symmetrical
and unsymmetrical biaryl compounds.
