文摘

Highly versatile and regioselective method for the synthesis of internal alkenes. Unique method for dehydrative cross-coupling/homo-dimerization/direct cross couplings. Successfully extended to the synthesis of novel benzopyrans. Solvent-free; step, atom economy and environmentally benign catalyst. Large substrate scope, high yields; user-friendly protocol.
