Organobismuth transition metal compound

Besides using sonochemistry as a means of promoting the pyrolysis of metal carbonyl compounds, ultrasound has been effective in the preparation of supramolecular organobismuth-transition metal carbonyls.The compound [ -BuBiFe(CO)4]oo has been formed by the reaction of -BuBr and [Et4N]3[Bi Fe(CO)4l4 in an ultrasonic cleaning bath in MeCN, followed by acidification. The reaction has been postulated to involve an ultrasound-generated radical mechanism.

Organobismuth compounds would have high potential as reagents for transition-metal catalyzed carbon-carbon bond forming reactions, because bismuth-carbon bonds are weak and can be easily cleaved by transition metals. The mean bond... 

There are several review articles that include descriptions of transition metal-catalyzed carbon-carbon bond formation of organobismuth compounds [5-10]. During the last decade, considerable development has been achieved in this area. However, there is no comprehensive review of this topic. Therefore, this review intends to comprehensively summarize transition-metal catalyzed carbon-carbon bond formation using organobismuth compounds.

The transition metals and their salts and coordination complexes such as RhCla, Pd(PPh3)4, Pd(OAc)2, Cu(0), CuCl and CuX2 can catalyze the aryl-aryl coupling, carbonylation and phenylation reactions of organobismuth compounds with indoles, acyl chlorides, acetylenes and olefins, as illustrated in Table 5.12. Most of these reactions proceed under mild conditions.
