The use of halogens in the crystal engineering supramolecular porphyrin assemblies has been a topic strong interest over past decades. With this mind we have characterized series direct meso-halogenated porphyrins using single X-ray crystallography. This is accompanied by detailed conformational analysis all deposited CSD. In study used Hirshfeld fingerprint plots together with normal-coordinat...

The paper “Enhanced reactivity of nitrogenous organohalogen formation from plant litter to bacteria," by Wang et al., presents a refreshing take on the natural formation of organohalogens, focusing on halogenation of bacterial cultures and monomers. The hypothesis is novel, the data are clearly presented and discussed, and the results are compelling. After reading the manuscript, I have a few l...

(Hetero)aryl bis-acid chlorides and terminal alkynes, or likewise acid chlorides and terminal dialkynes, and ethyl 2-mercaptoacetate can be reacted to give highly luminescent symmetrical terthiophenes and quinquethiophenes in the sense of a consecutive pseudo-five-component reaction in good to excellent yields. Further functionalization of the obtained oligomers can be readily achieved by halog...
