One of the best things in science, that there are several ways to prove something. Check our paper at Nature Catalysis: https://t.co/Kzg8XCpGUY.
See the other papers @KazunoriKoide and @bedcatalysis !

Have you ever encountered difficulties with C-H Activation of your ortho-substituted aromatic compounds? Or steric repulsions were suspected?🧐 Find more about the Ortho Effect from this paper at RSC @ChemicalScience

@KazunoriKoide @PeONor It worked like a charm! Koide's Pd sensor should be at the side on the TLC plates in every lab!

@ViktoriaGessner Thanks!

We tried to settle a highly heated debate here on twitter. This is how a research topic is born :).
Pd impurities can be present after chromatographic purification and catalyze Suzuki coupling. See on ChemRxiv: https://t.co/GM9amzzm3v

@awhspeed @ndchiappini We actually had problems with the benzynes from the I(III). We blamed them for the bad selectivity.

[tolnailab @tolnailab]

@awhspeed @ndchiappini Thanks! Some of us pulled some 100 hours work week for a month. Iodonium salts are somtimes picky....

[tolnailab @tolnailab]

@ndchiappini We have done the same mistake earlier. Working on a topic for long, to realize, catalyst was an impurity. We really hope that this will help others not to make the same mistake.

[tolnailab @tolnailab]

@PeONor We did not want to make an educated guess for the vote, so we looked into it. Now our highly educated vote goes for the Pd in amine version. See details on ChemRxiv: https://t.co/GM9amzzm3v

Our paper on catalytic ring opening of [1.1.1]propellane was highlighted in one of the best organic chemistry pages on the web: https://t.co/nDDLr8HroO

Thanks @organic_portal !

Done some preliminary experiments for a prospecting future collaboration. It was a very nice experience. More info hopefully in a few weeks.

Molten lead. It is very easy to melt it if you have some powerful burners at home. Young kids probably never seen molten metal before. It is also very nice to observe the density of the… https://t.co/4oQzM4MyxJ

Collecting liquid oxygen with strong permanent magnet. It is very nicely visible where the magnetic field is the strongest.

Kind of obsessed with stacked pasteur pipettes and test tubes. They kinda look the same, but you never know wich one will help finish the last step of your synthesis.

Not rocket science! Small rockets made of alminium foil. You have to be a little carful, but they can fly very far in an open space.

The reaction of water with lithium. The hydrogen is lit by match to see flame coloring. The water is dyed by kongo red to see pH switch.

Using a syringe pump to make #propellane is so much easier then adding it dropwise by hand!
The brown solution is phenyllithium, added to the cyclopropane derivative in the flask, while cooled.
