Originally known as a double replacement or double displacement reaction, for 10 points, name this general class of reactions with a well- known olefin version.
Furnster in an elegant alkyne type of this reaction utilizes the fact that partial reduction of the triple bond using Lindlar-type procedures gives access to any given isomer at will. Also in this type of reaction metal- carbenes such as Shrock and Grubbs type will serve as catalyst precursors in this type of reaction. An example of this type of reaction involves silver nitrate and salt to yield Silver chloride and sodium nitrate. In another type of this reaction involves exchanging of carbon-carbon double bonds between alkenes.

Metathesis Reaction [do not accept Olefin Metathesis after "silver nitrate" accept double dis/  replacement before mentioned]
