Pyrazole preprint palooza: making C-N bonds and using variable time normalization analysis kinetics🎢. Take a peak at Alex, ⁦@HannahSlocumb5⁩, and Xiaohui’s ⁦@UCIChemistry⁩ collaboration with Charles ⁦@Merck⁩ ⁦@ChemRxiv⁩ https://t.co/21AKwfOsN4

I'm excited to see our Perspective article on tandem catalysis featuring stereoselective hydrogenation published in JACS. Thanks to Xintong and @Vy_Dong_Group for being an amazing team to work with!

Check out this amazing work from my awesome lab mates @NieShaozhen, Alex Lu, and @ErinKuker @Vy_Dong_Group

[VyDong @Vy_Dong_Group]

Congrats @NieShaozhen, Alex, and @ErinKuker--so proud of your efforts! Check out our latest idea for making enantiopure sulfides @J_A_C_S @UCIChemistry: https://t.co/Px1K5aQ7NV

@basker25071980 @Vy_Dong_Group @UCIChemistry Thank you, we have not explored non-phosphine ligands with this system. However, we are definitely interested in seeing if other metals can catalyze related transformations.

Back for another year of the #RSCPoster Twitter Conference! This year I'm sharing a project from the @Vy_Dong_Group at @UCIChemistry that focuses on the 'Enantioselective Addition of Nitroesters to Alkynes'.

@DonnardMorgan @Vy_Dong_Group @UCIChemistry Thanks! We have briefly looked at non-aromatic internal alkynes and unfortunately they are unreactive. We attribute the loss in reactivity to sluggish isomerization of the alkyne to the allene intermediate.

[Ryan Davison @RyanDavoChem]

@anatmilo @Vy_Dong_Group @UCIChemistry Thank you! Given the types of ligands we examined there was not a clear trend between electron donating groups and selectivity. The placement, size, and potential inductive effects appear to be major contributors to selectivity. The optimal MeO-BIPHEP ligand was in its own class.

[Ryan Davison @RyanDavoChem]

Come see how the @Vy_Dong_Group is teaching aldehydes new tricks using Rh and Co catalysis. This was a fun account to write with @ErinKuker!

Excited to see our work on the synthesis of amino acid precursors published in ACIE. Thanks to @pdpark16 , Xintong, Crystal, Sara, and @Vy_Dong_Group for being an amazing group to work with!

[Ryan Davison @RyanDavoChem]

@Vy_Dong_Group @DrMikeBooth I can confirm 😂

[VyDong @Vy_Dong_Group]

We're making alkyne of amino acids--thanks to @RyanDavoChem @pdpark16 Xintong, Crystal, and Sara @UCIChemistry

Tomorrow we will be participating in #ShutDownSTEM and #ShutDownAcademia to #Strike4BlackLives.

It is not enough to say these things, we must ACT. Check out the resources at https://t.co/310S5dw6bi for ways to make a difference. We all have a role in eliminating racism.

The Three Masketeers

[Shaozhen Nie @NieShaozhen]

Shopping with my two bro, with mask, glove, and IPA, like one scene of movie. And you can give one name for this movie.

[Ryan Davison @RyanDavoChem]

@raynal_cnrs @Vy_Dong_Group Thank you! Rh(cod)2BArF gives the same isomer as Rh(cod)2SbF6, but in slightly lower yields.

Excited to share these collaborative projects from the @Vy_Dong_Group at UC Irvine! Metal–Hydride Catalysis: Hydrofunctionalizations of Dienes #RSCPoster #chemtwitter #catalysis

[Ryan Davison @RyanDavoChem]

@HamaadMoustafa @Vy_Dong_Group The hydrothiolation work can be found here: https://t.co/z4d01xkrSn and https://t.co/CYHgcHAA5n

[Ryan Davison @RyanDavoChem]

@HamaadMoustafa @Vy_Dong_Group Spot on, thiols are typically thought of as catalyst killers, but in the case of our Rh catalyst we don’t observe any inhibition when adding excess thiol.

[Ryan Davison @RyanDavoChem]

@scscembellin @Vy_Dong_Group Great question: we also see that amines and alcohols participate in the reaction, but with slightly different conditions.

[Ryan Davison @RyanDavoChem]

@andrei_yudin @Vy_Dong_Group Thanks! We do observe small amounts of thiol alkylation at higher temperatures and/or with catalysts that do not give high conversion.
