Question

$RC{O}_{2}Ag+B{r}_2\stackrel{CC{l}_4}{\to }?$

What is the final product of the given reaction?

Answer 1

$RC{O}_{2}Ag$ converts to $RBr$ when reacted with dibromine ($B{r}_2$) and $CC{l}_4$ as reagent. This reaction is known as Hunsdiecker reaction in which carboxylic acids are converted to the chain-shortened halide. The carboxylic acid is first converted to its silver salt , which is then oxidized with halogen.

$CC{l}_4$

$RC{O}_{2}Ag+B{r}_2\to RBr+C{O}_2+AgBr$
