Third structure slip-up for chemist in Korea yields retraction

Chem_ak3Authors of a 2010 Chemistry – A European Journal article have retracted it “due to the wrong assignment of structure” of catalysts.

The retraction is the third, by our count, for corresponding author Doo Ok Jang, a chemist at Yonsei University in Wonju. Jang authored one of the previously retracted papers with Sung Jun Kim and the other with Sang Yoon Kim. Both papers were also sunk by misassigned structures.

The current study, “Enantioselective Radical Addition to Ketimines: A Synthetic Route Towards α,α-Disubstituted α-Amino Acids,” is authored by all three chemists. Here’s the retraction notice:

Plagiarism: It’s just an “approach” to writing papers, right?

chemistry coverWe’ve heard a lot of rationalizations for plagiarism on this beat — “I didn’t know I had to cite that text”; “That author said it better than I ever could”; etc. — but here’s a new one for the wall of shame.

Chemistry – A European Journal is retracting a 2012 article, “A New Indicator for Potassium Ions at Physiological pH by Using a Macrocyclic Luminescent Metal Complex,”  by a group of Chinese authors who used the cut-and-paste method to put together their manuscript. That’s not unusual. But the notice is:

University of La Laguna ethics committee finds evidence of misconduct in chemists’ papers

jacsat_v134i049.inddA committee at the University of La Laguna (ULL), in Spain’s Canary Islands, has found evidence of misconduct by two chemists in at least two papers. One of those authors had already been forced to retract a paper in the Journal of the American Chemical Society (JACS).

The story is complicated. Here’s a try at telling it: Continue reading University of La Laguna ethics committee finds evidence of misconduct in chemists’ papers

Did a McLuhan moment lead to retraction in Chemistry — A European Journal?

The authors of a chemistry paper are retracting it after a Columbia University chemistry researcher pointed out a fatal misinterpretation of his own work in it.

Here’s the notice in Chemistry — A European Journal: Continue reading Did a McLuhan moment lead to retraction in Chemistry — A European Journal?
