cross-coupling to construct the C(sp2)–C(sp3) bond was developed from two sustainable biomass-based feedstocks: phenolderivatives with umpolung aldehydes. This strategy features the in situ generation of moisture/air-stable hydrazones from naturally abundant aldehydes, which act as alkyl nucleophiles under catalysis to couple with readily available phenolderivatives. The avoidance of using both halides

various substituted indoles. This method has been successfully extended to the synthesis of diverse trifluoromethylated triarylmethanes employing phenols as nucleophiles. Furthermore, the potential of the method was demonstrated via the two-step synthesis of a trifluoromethylated analog of a hypolipidemic and anti-obesity agent.

Palladium Catalyzed Arylation and Benzylation of Nitroarenes Using Aryl Sulfonates and Benzyl Acetates
Pd-catalyzed arylation or benzylation of nitroazoles using aryl sulfonates or benzyl acetates is described. Electronically varied aryl tosylates and mesylates, as well as benzyl acetates, afford the arylated and benzylated products. Arylation of nitrobenzene is also reported. The relative rate for the arylation of halides is greater than that of tosylates using the reported reaction parameters. These studies enhance the scope of electrophiles for nitroarene arylations and benzylations, which was hitherto limited to the use of halide electrophiles.
