complementary Ni-based catalyst system that employs simple unligated Ni(II) salts as an inexpensive alternative to the Pd-based systems for the borylation of aryl (pseudo)halides. Extrapolation of all three systems to a one-pottandemborylation/Suzuki–Miyauracross-coupling is also demonstrated on advanced intermediates and drug substances.

The anodic oxidation of oxygenated biphenyls produces phenyl-substituted -quinol ether ketals in good-to-excellent yield. These compounds are useful substrates for preparation of more highly functionazized biphenyls.

for carbamate-directed -C-H bond arylation of biphenyl derivatives employing diaryliodoniumsalts as the arylation agents was explored. Consequently, the Scholl reaction was utilized to cyclize the product, yielding 21 varieties of multifunctional triphenylene derivatives. The maximum yield achieved through this two-step process was 94 %, offering an efficient synthesis route for the production of multi-substituted
