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
