- Abstract (EN)
- We describe the synthesis of seven C2-alkylcarbazoles via a sequence of Buchwald–Hartwig coupling of arylamines with aryl halides followed by oxidative cyclization of the resulting diarylamines. Methyl groups at the positions 4 and 5 were introduced by taking advantage of the ortho-directed palladation of meta-pivaloyloxy-substituted diarylamines and subsequent conversion of the pivaloyloxy to methyl groups through Stille coupling of intermediate triflates. The obtained ethyl- and dimethylcarbazoles served as analytical standards for their identification in petroleum samples and source rocks.
