Abstract

Suzuki reactions are utilized for the synthesis of heterobifunctional cross-linking reagents (thiol- or aminospecific and photoactivatable), polyaromatics (such as phenanthrene) and heterocycles (such as coumarin and quinoline), anellated nitroxides and paramagnetic, biologically active molecules (such as cis-stilbene and nicotinamide). Furthermore, the synthesis of new vinyl and allyl boronic acid esters is also reported.

Key words

boron - cross-coupling - free radicals - heterocycles - palladium
