[reaction: see text] 2-Triethylsiloxy-substituted 1,3-butadiene has been prepared in gram quantities from chloroprene via a simple synthetic procedure. Silatrane and catechol-substituted analogues of this main group element substituted diene were prepared by ligand exchange and characterized by X-ray crystallography in addition to standard spectroscopic techniques. Diels-Alder reactions of these dienes

standard spectroscopic techniques. 2-Dimethylphenylsilyl-1,3-butadiene has also been prepared from chloroprene on an 8-g scale. Diels−Alderreactions of these dienes are reported as well as subsequent TBAF-assisted/Pd-catalyzed Hiyama cross-coupling reactions of those Diels−Alder adducts. Silicon-substituted cycloadducts and cross-coupled products were also characterized by NMR spectroscopy and, in two
