A highly regioselective and atom-efficient strategy for the construction of fused free (NH) heteroarenes through a palladium-catalyzed perfluoroalkyl insertionreaction has been accomplished. This protocol employed multiple iodofluoroalkanes as practical and available perfluoroalkyl sources to provide an operationally simple and versatile route for the synthesis of perfluoroalkylated indoles.

Addition of polyfluoroalkyl halides to alkynes and alkenes bearing a variety of substituents is effected by the catalysis of iron, cobalt and ruthenium carbonyl complexes to give the corresponding adducts in good to excellent yields under mild conditions.
Halogenated .alpha.-amino acids as new compounds are obtained by subjecting halogenated ethanes and an ester of acrylic acid or crotonic acid to addition reaction, adding sodium azide to the adducts, reducing the resultant mixtures with hydrogen and subsequently hydrolyzing the reduction products.
