Selective meso-monobromination of 5,15-diarylporphyrins via organopalladium porphyrins
Kato, Aiko, Hartnell, Regan D., Yamashita, Masahiro, Miyasaka, Hiroshi, Sugiura, Ken-ichi, & Arnold, Dennis P. (2004) Selective meso-monobromination of 5,15-diarylporphyrins via organopalladium porphyrins. Journal of Porphyrins and Phthalocyanines, 8(10), pp. 1222-1227.
The selective meso-monobromination of 5,15-diarylporphyrins is difficult to achieve and extensive chromatography is required to obtain pure products. A sequence of (i) dibromination, (ii) selective monoinsertion of [Pd(dppe)] [dppe = 1,2-bis(diphenylphosphino)ethane] and (iii) hydrodepalladation using methanolic base affords pure monobromoporphyrins in typically ≥60% overall yield without isolation of the organopalladium porphyrin. Monobromo derivatives of even highly lipophilic 5,15-diarylporphyrins are thus readily available without tedious, expensive and environmentally undesirable chromatography.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
