Pentaorganoantimony compounds

Various alkyl and aryl substituted pentaorganoantimony compounds are known, however pentaorganobismuth compounds have been limited to aryl substituted compounds. Most of this type of compound has been synthesized by transmetallation from Grignard reagents or organolithium reagents to antimony and bismuth centers. 

Tetraorganoantimony azides have been prepared from the reaction of pentaorganoantimony compounds with HNj (equation 249) . 

Reaction of pentaorganoantimony and -bismuth compounds with acids gives the corresponding oxygen compounds. Several examples are shown in equations...
