Sonochemical synthesis of bis(tri-n-butylstannyl) aromatic compounds via Barbier-like reactions

Abstract

The best reaction conditions and the syntheses of some new bis(tri-n-butylstannylated) aromatic and heteroaromatic compounds by means of a Barbier-like sonochemical reaction are reported. Full 1 H-, 13 C-, and 119 Sn-NMR data of the new organotin compounds are informed.

Efficient One‐Pot Cross‐Coupling of Two Aryl Halides by Stannylation/Stille Reaction in Water under Microwave Irradiation

“…Since then, this method has been extensively used to stannylate aryl halides or aryl trifluoromethanesulfonates 16–19. More recently, the sonochemical Barbier reaction of aryl bromides has also been reported to synthesize successfully aryl stannanes 20. All of these stannane preparations require isolation/purification procedures, which are often troublesome and inevitably lead to toxicity and environmental concerns, and the Stille reaction consists of a tedious multipot synthetic sequence and is, of course, inefficient in terms of step economy (Scheme ).…”
