An efficient conversion of bis-silylated dienes and trienes into polyenylsilanes by cross-coupling reactions is described. The aryl substituted polyenes are synthesized by ipso-borodesilylation with BCl3 followed by Pd-catalyzed coupling reactions of the resulting boron derivative with aryl halides, whereas the synthesis of alkyl substituted polyenes requires the conversion of the boron intermediate into iodo-derivative and the subsequent coupling with alkyl Grignard reagents in the presence of a Ni(II) catalyst.

Aldehydes are converted to the corresponding (E)-alkenylsilanes with one carbon homologation by means of a gemdichromium reagent prepared by CrCl2 reduction of Me3SiCHBr2 in THF.Transformation of aldehydes into alkenyl sulfides is also achieved with a com
