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

[reaction: see text] 2-BF3-substituted 1,3-butadienes with potassium and tetrabutylammonium counterions have been prepared in gram quantities from chloroprene via a simple synthetic procedure. The potassium salt of this new main group element substituted diene has been characterized by 1H, 13C, 11B, and 19F NMR. Diels-Alderreactions of these dienes with ethyl acrylate and methyl vinyl ketone are reported

reactivity in Diels–Alderreactions has been examined and the boron substituted cycloadducts of those cycloaddition reactions have been used in cross coupling reactions. One-pot tandem Diels–Alder/cross coupling reactions of 2-boron substituted dienes are then also reported along with some experimental evidence that these one-pot reactions are proceeding through a Pd(II)-catalyzed Diels–Alder/cross coupling

of 1,7‐octadiene as an in situ source of ethylene led us to develop a novel multicomponent tandem cross‐enynemetathesis (CEYM)‐Diels–Alder reaction. The process can be considered a relay metathesis, in which the ethylene liberated in the ring‐closing metathesis (RCM) of 1,7‐octadiene initiates the tandem sequence. Aliphatic, aromatic, and fluorinated alkynes and several dienophiles are compatible with
