Tributylethynylstannane are connected to the substrate molecule sp2 hybrid carbon iodine atoms in Pd catalyst under the action of cross coupling reaction, the introduction of acetylene in the substrate molecule is typical of the substrate molecule alkenyl iodine and aryl iodide many different kinds of commodity is the reaction of Pd catalyst, laboratory regular Pd (PPh3) 4 can meet the needs of the reaction, in general, the reaction can be carried out in very mild conditions, the general can be a few minutes at room temperature to within a few hours to complete the reaction efficiency and product yield is very high (type 1 ~ 3) [3 ~ 5].If diiodoaryl compounds are used, diacetylenyl iodine can be obtained (equation 4).

Heat up Tributylethynylstannane with a compound of tetrazine ,the tetrazine compound reacts with Tributylethynylstannane [4+2] while releasing nitrogen , got the compound product of diazine substituted by tributyltin was obtained (equation 5) .Recently, it has been reported that in the presence of nickel catalyst, tributyltin self coupling, the formation of enyne products is also a very significant result (equation 6).
