Screenshot of Holden Thorp's skeet that says: Hi, this is Holden emerging from my Bluesky hiatus to tell everyone that when checking the links in the piece, I used ChatGPT as my search engine (does anyone use Google anymore?). The piece was written by me and edited by humans. So all the links were checked by me and again by our copyeditors.

Purported synthesis of graphyne from hexabromobenzene (or benzene!). Of all the things that did not happen, this one did not happen the most.
“All of these substances can be called marker reagents, but it is precisely 1,8-diazabicyclo[5.4.0]undec-7-ene that is the most important among them. Someone might even call it a precursor, but that would be incorrect, since a precursor is the base to which another substance is added to obtain the target compound, so in this case we are dealing with that second substance. Among all the other reagents, which may include ordinary solvents, this is the most reliable marker.”
1,8-Diazabicyclo[5.4.0]undec-7-ene also known affectionately as DBU. Possibly one of the most common organic bases.
A table with compounds listed in the published synthesis of epibatidine. The key molecules of interest are 3-buten-2-one (aka methyl vinyl ketone), and 6-chloropyridine-3-carbaldehyde, as the only molecule structurally related to the target alkaloid.

Scanning probe microscopy of a γ-graphyne film synthesized using water-soluble Pd(TPPTS)3. (A) Lateral deflection map of a re-gion of the film. (B) Periodicity of the low-pass filtered lateral deflection maps for the HOPG reference and γ-graphyne. Colored bars mark the confidence intervals for lattice constants.
Interfacial synthesis of γ-graphyne. (A) Batch synthesis of Br-edge γ-graphyne (GY-Br) through 2D polymerization of TBTEB monomer. (B) Interfacial synthesis of γ-graphyne using a lipophilic Pd(PPh3)4 pre-catalyst. Both the catalyst and TBTEB monomer are in organic solvent. (C) Interfacial synthesis of γ-graphyne using a water-soluble Pd(TPPTS)3 pre-catalyst. The TBTEB monomer is in the organic solvent, while the catalyst is in water.
