bond at either the meta or para position by only changing the catalyst system poses a significant challenge. We herein report the [Fe(TPP)Cl]-enabled, selective, C-H difluoromethylation of arenes using BrCF2CO2Et as the difluoromethylation source, which successfully altered the selectivity from the meta to the para position. A preliminary mechanistic study revealed the iron porphyrin complex not only

We have developed a new strategy that uses the Krohnke synthesis for the preparation of various substituted phenylpyridines in excellent yields (up to 88 %). Starting with the appropriate commercially available acetophenone, a variety of phenylpyridines substituted by either electron-donating (i.e. methyl, methoxy) or -withdrawing groups (i.e. bromide, nitro) on the phenyl ring are obtained in a two-step

A facile and efficient protocol for palladium-catalyzed ortho-acylation of 2-aryl pyridines was developed. Note that this acylation utilized arylmethyl amines as new, cheap and readily available acylation reagents and exhibited high regioselectivity for 2-aryl pyridines bearing a meta-substituent in the aryl ring moiety.
