Xa. Zhou et al., SYNTHESIS OF BETA-MONOSUBSTITUTED, TETRASUBSTITIUED, AND OCTASUBSTITUTED STERICALLY BULKY PORPHYRINS VIA SUZUKI CROSS-COUPLING, Journal of organic chemistry, 61(11), 1996, pp. 3590-3593
beta-Mono-, tetra-, and octasubstituted tetramesitylporphyrins were pr
epared in good yields by Suzuki cross-coupling reactions of of beta-br
omotetramesitylporphyrins with aryl- and alkylboronic acids.
