# Why is simple metathesis not the result of the reaction between an alkyl halide and silver cyanide?

R-X + Ag^(+)""^(-)C-=Nrarr R-C-=N + AgXdarr
And as you know, silver halide is as soluble as a brick, and this drives the $C - C$ bond formation. Of course, redox processes could occur, and hydrocarbon may be oxidized.
