Metal-Free Synthesis of Amides by Oxidative Amidation of Aldehydes with Amines in PEG/Oxidant System. — A green, simple, inexpensive, and efficient one-pot synthesis of amides using a PEG/oxidant system is reported. The environmen-tally benign of the method makes it a useful supplement for those known strategies. — (LIANG, J.; LV, J.; SHANG*, Z.-C.; Tetrahedron 67 (2011) 44, 8532-8535, http://dx.doi.org/10.1016/j.tet.2011.08.091 ; Dep.
