reaction between vinyl-, allyl- and but-3-ene-1-yl-trimethylsilanes and teh dime [Pt2Cl4(C2H4)2]. It is followed by the cleavage of the activated SC bond of the first two silanes. The nature of the Pt(II) complexes giving this reaction and the comparison of their activity with that of protic acids is discussed. It is shown that the cleavage of the SiC(sp2) bond of but-2-ene-2-yltrimethylsilanes is stereospecific
