Z-1,2-Bis(trimethylstannyl)-1-alkenes show different types of reaction behaviour towards various electrophiles. p-Tolysulphonyliso-cyanate forms five-membered tin-nitrogen-containing heterocycles. 1,1-Dichloromethylmethyl ether reacts with carbofunctionalised distannylalkenes to yield α,β-unsaturated aldehydes, which are useful tools for the synthesis of further substituted vinylstannanes. Z-1,2-Bis(trimethylstannyl)- 1-alkenes containing heteroatoms such as O or N undergo only protodestannylation with this electrophile. The reaction of Z-1,2-bis (trimethylstannyl)-1-alkenes with trimethylsilyl chlorosulphonate followed by hydrolysis with aqueous NaHCO3 provides the corresponding sodium sulphonates. SO2 and SO3 undergo insertion into both tin-carbon bonds in an ipso- and stereospecific manner to form bis-sulphinic- or bis-sulphonic bis(trialkylstannyl) esters.

The silicon-tin bond in Me3SiSnR3 (R=Me, n-Bu) adds regio- and stereospecifically to 1-alkynes and also to a limited number of nonterminal alkynes when Pd(PPh3)4 is added as a catalyst.The use of the (Z)-silylstannylalkenes thus formed in synthesis either
