Infrared Irradiation-Assisted Pd-Catalyzed C(sp³)─H Arylation and Tandem Cyclization of Ortho-Tolualdehydes. [PDF]

Chemistry
A rapid and efficient protocol for the synthesis of 2‐benzylbenzaldehydes and anthracenes is reported, based on the infrared (IR) irradiation‐assisted Pd‐catalyzed C(sp3)─H arylation and the tandem C(sp3)─H arylation/electrophilic aromatic cyclization of ortho‐tolualdehydes with aryl iodides via a transient directing group (TGD) strategy.

Direct catalytic arylation of heteroarenes with meso-bromophenyl-substituted porphyrins

Beilstein Journal of Organic Chemistry, 2017
The arylation of mono-, di- and tetra-meso-bromophenyl-substituted porphyrins with the heteroarenes containing “acidic” C–H bonds, such as benzoxazole, benzothiazole and N-methylimidazole was studied in the presence of three alternative catalytic systems:
