An orthogonally arranged conjugate comprised of two rhodium(III) tetrakis-4-tolyporphyrins linked with an azobenzene moiety through a covalent Rh-C (aryl) bond has been facilely synthesized and characterized. Although photochemical isomerization of t

Flipped-classroom learning has been shown to improve students’ learning experience and performance in tertiary education. However, few studies have been done in Asia where the learning culture is vastly different from the West. Here, we studied the

Base-promoted aerobic carbon–hydrogen bond activation (CHA) of thiophene was achieved with high regioselectivity at the 2-position by group 9 metalloporphyrins in moderate to high yields. Mechanistic investigations suggest a homolytic aromatic subs

Base-promoted vinyl carbon–bromine bond cleavage of styryl bromide by group 9 metalloporphyrin complexes was achieved to give the metal(III) porphyrin styryls M(ttp)(styryl) (ttp = 5,10,15,20-tetra-p-tolylporphyrinato dianion). Mechanistic studies

Direct C–H arylation of unactivated heteroaromatics with aryl halides catalyzed by cobalt porphyrin is reported. The reaction is proposed to go through a homolytic aromatic substitution reaction. The aryl radical is electrophilic and a SOMO–HOMO
