This work emphasizes the synthesis of substituted vinyl arenes by reductive coupling of arylhalides with vinyl bromides under mild and easy‐to‐operate nickel‐catalyzed reaction conditions. A broad range of arylhalides, including heteroaromatics, and vinyl bromides were employed to yielding products in moderate to excellent yields with high functional‐group tolerance. The nickel‐catalytic system displays
Without the formation of inseparable regioisomers, various substituted phenol derivatives 2 and benzene derivatives 4 were prepared through RCM-tautomerization and RCM-dehydration protocols. A new synthetic route to precursors 1 and 3 enabled efficient access to these aromatic compounds.

The present invention relates to the identification and use of antigen-binding regions, antibodies, antigen-binding antibody fragments and antibody mimetics, neutralizing the anti-coagulant effect of an anticoagulant in vitro and/or in vivo. Antibodies and functional fragments of the invention and antibody mimetics can be used to specifically reverse the pharmacological effect of an anticoagulant e.g. a FXa inhibitor for therapeutic (antidote) and/or diagnostic purposes. The invention also provides nucleic acid sequences encoding foregoing molecules, vectors containing the same, pharmaceutical compositions and kits with instructions for use.
