The push-pull electronic and steric effect of copper porphyrin catalysts on the cross-dehydrogenative coupling (CDC) reaction between the hydroxyl group of phenol substrates and C(sp3)-H bond have been investigated. Results showed that copper porphyrin bearing electron-withdrawing, bulky steric hindrance or heteroatom of pyridyl groups could increase the catalytic activity in the reaction. 5,10,15,20-(tetrakis(4-pyridyl)porphyrin)copper (CuTPyP) was found the best among all tested catalysts. Phenol substrates bearing various functional groups afforded moderate to excellent yields (99%). Significantly, as compared to other tested copper porphyrins, CuTPyP not only exhibited remarkable higher activity but also could shorten the reaction time from 12 to 6 h.

K2S2O8mediated synthesis of 5-Aryldipyrromethanes and meso-substituted A4-Tetraarylporphyrins

The synthesis of dipyrromethanes from pyrrole and arylglyoxylic acids in the presence of K2S2O8at 90 C is reported affording dipyrromethanes in very good yields. Unlike an excess pyrrole traditionally used in dipyrromethane synthesis, the current method uses a stoichiometric amount of pyrrole avoiding any use of Br?nsted or Lewis acid. A gram scale synthesis of 5-phenyldipyrromethane is also achieved demonstrating potential scale up of dipyrromethanes using this method feasible. Subsequently, dipyrromethanes were converted to A4tetraarylporphyrins also in the presence of K2S2O8at 90C. A direct synthesis of A4-tetraphenylporphyrin from excess pyrrole and phenylglyoxylic acid in the presence of K2S2O8 at 90C is also reported.

Appropriate and efficient way for the preparation of 3-allyl-2,3-dihydro-2,3′-bisindoles has been developed via homocoupling of N–H indole. Pd-porphyrin-catalyzed allylation of indoles with allylic alcohols in the presence of PBr3 and a base is developed. The reaction involves dimerization at the C3 and C2 positions of the indoles, giving 2-allylated 3-(indolin-2-yl)-1H-indoles in moderate to good yields. 3-(Indolin-2-yl)-1H-indole derivatives serve as intermediates for the synthesis of pharmaceutically active molecules.
