An efficient, mild and practical approach for the synthesis of amides from nitriles and peroxides is reported in the presence of boron trifluoride ethereate. In this protocol, we utilized peroxides as C1 synthons for the amidationreaction. Also, we successfully prepared boron‐containing β‐ketoamides in a one‐pot assembly from β‐ketonitriles. A variety of functional groups were tolerated in moderate
Novel radiopharmaceuticals that are useful in diagnostic imaging and therapeutic treatment of disease characterized by overexpression of seprase include complexes that contains a proline moiety and a radionuclide adapted for radioimaging and/or radiotherapy:
Cp*Co<sup>III</sup>-Catalyzed Dehydrative C–H Allylation of 6-Arylpurines and Aromatic Amides Using Allyl Alcohols in Fluorinated Alcohols
Cp*CoIII-catalyzed C–H allylation of various aromatic C–H bonds usingallylalcohols as allylating reagents is described. Improved reaction conditions using fluorinated alcohol solvents afforded efficient directed C–H allylation of 6-arylpurines, benzamides, and a synthetically useful Weinreb amide with good functional group compatibility.

convenient new strategy for producing radiolabeled compounds in high effective specific activity was developed usingsoluble fluorous supports. The reported methodology involves a fluorous linker group that is released from the substrate of interest upon reaction with radioiodine. The desired product can then be selectively separated from unreacted starting material and reaction byproducts using a simple
