Abstract

On the Reactivity of Silaethene Me 2 SiC(SiMe 3 ) 2 : Stereospecificity of Diels‐Alder Reactions with Hexadienes 1,2 ) [4 + 2] Cycloaddition of trans,trans ;‐ and cis,trans ;‐2,4‐hexadiene to silaethene Me 2 SiC(SiMe 3 ) 2 ( 1 ) takes place stereo‐specifically in one step with formation of 3 and 4 , respectively. In addition, both reactions lead to ene products 5, 6 .
