I am glad to see our @hering_lab study now published in @ChemEurJ!

[Jan-Erik Siewert @siewert_jan]

Was a really cool study with interesting structures. The Ar3P3 are very good P-Transfer agents. Hopefully these NHP systems can provide the ground for more to follow. Thanks to everyone involved.

Iron and rhodium coordination chemistry and catalysis with a chelating bisphosphinidene ligand donating up to eight electrons! Very enjoyable working with @C_HJunghans and @siewert_jan of the @hering_lab on this project! With Braulio Puerta Lombardi, who is not on Twitter. Yet.

@siewert_jan from @likat_rostock is kicking off the afternoon’s session with his talk “Synthesis and coordination of novel chelating Bis(NHC-phosphinidene) ligands”. Some beautiful #phosphorus #chemistry on display at the #19EWPC #3SWPC.

Beautiful talk by Jan-Erik Siewert on bis(phosphinidene) ligands. @hering_lab @likat_rostock

@H_H_Hydrogen @RoySocChem @RolandRoesler @hering_lab I think it might be due to the flexibility of the linker and thus bite angle change

Bidentate NHC-stabilized Bis(phosphinidenes) - Happy to share my recent work at the RSC Twitter Conference. @RoySocChem
A fruitful collaboration with @RolandRoesler and @hering_lab.

@AdityaBasu2001 @RoySocChem @RolandRoesler @hering_lab There is one paper out for the activation of CO2 https://t.co/V7tAE7inlV

@Bindusa64475075 @RoySocChem @RolandRoesler @hering_lab We synthesized Dip3P3 starting from DipPCl2. https://t.co/BYRyUNofuT

@CLuChem @RoySocChem @RolandRoesler @hering_lab That is a really good idea :) we have done CV studies on the Ligand 3a and Rh(cod) complex 5

[Jan-Erik Siewert @siewert_jan]

@SharmaaMahendra @RoySocChem @RolandRoesler @hering_lab We didn’t investigated the chemistry towards Lewis Acids. For monodentate NHC-stabilized phosphinidenes it’s known that AlCl3 or BPh3 can extrude the P-unit

[Jan-Erik Siewert @siewert_jan]

@ME_Moret @RoySocChem @RolandRoesler @hering_lab The ligand is quite flexible due to the CH2 linker. The bite angle ranges from 86° (5 Rh(cod)) to 106° (4 FeBr2).

@Dr_Oli_Jones @RoySocChem @RolandRoesler @hering_lab Sorry for the inconvenience. I misread the time

[Jan-Erik Siewert @siewert_jan]

@RoySocChem @RolandRoesler @hering_lab Thanks to @NoraJannsen for the catalytic studies :)

[Jan-Erik Siewert @siewert_jan]

@DielmannGroup @PawelLoewe @OGManchenoLab Congratulations Pawel 🎉🎓

[Jan-Erik Siewert @siewert_jan]

@JvLGermany @OVGUpresse Congratulations 🎉 🥳

[Jan-Erik Siewert @siewert_jan]

Some very beautiful views indeed

[Roland Roesler @RolandRoesler]

Nice views while ascending Mount Rae in # #Kananaskis. With Braulio Puerta, @siewert_jan and @Achaxis. In real time.
