Metal-Organic Frameworks Invert Molecular Reactivity: Lewis Acidic Phosphonium Zwitterions Catalyze the Aldol-Tishchenko Reaction

Gerald Bauer, Berend Smit, Daniele Ongari, Davide Tiana, Xiangru Xu

The influence of metal-organic frameworks (MOFs) as additives is herein described for the reaction of n-alkyl aldehydes in the presence of methylvinylketone and triphenylphosphine. In the absence of a MOF, the expected Morita-Baylis-Hillman product, a beta ...

A Novel Nickel Pincer Complex in the Active Site of Lactate Racemase

Xile Hu, Gerald Bauer, Tao Xu

A recent study revealed the structure of the Ni-containing active site of lactate racemase. The Ni is coordinated by a SCS pincer ligand derived from a nicotinic acid mononucleotide. ...

Recent developments of iron pincer complexes for catalytic applications

Xile Hu, Gerald Bauer

Iron catalysis is attractive for organic synthesis because iron is inexpensive, abundant, and non-toxic. To control the activity and stability of an iron center, a large number of iron pincer complexes have been synthesized. Many such complexes exhibit exc ...

Cross-Coupling of Nonactivated Primary and Secondary Alkyl Halides with Aryl Grignard Reagents Catalyzed by Chiral Iron Pincer Complexes

Xile Hu, Gerald Bauer, Chi Wai Cheung

Iron(III) bisoxazolinylphenylamido (bopa) pincer complexes are efficient precatalysts for the cross-coupling of nonactivated primary and secondary alkyl halides with phenyl Grignard reagents. The reactions proceed at room temperature in moderate to excelle ...

Catalytic Applications and Mechanistic Investigations of Iron Bis(oxazolinylphenyl)amino Pincer Complexes in Kumada Cross Coupling and Hydrosilylation Reactions

Gerald Bauer

The aim of the project was to investigate iron bis(oxazolinylphenyl)amino (bopa) pincer complexes as pre-catalysts in the enantioselective Kumada cross-coupling of non-activated alkyl halides with aryl Grignard reagents. From this preliminary cross-couplin ...

Iron Pincer Complexes as Catalysts and Intermediates in Alkyl Aryl Kumada Coupling Reactions

Rosario Scopelliti, Matthew Wodrich, Xile Hu, Gerald Bauer

Iron-catalyzed alkylaryl Kumada coupling has developed into an efficient synthetic method, yet its mechanism remains vague. Here, we apply a bis(oxazolinylphenyl)amido pincer ligand (Bopa) to stabilize the catalytically active Fe center, resulting in isola ...

Solid-state proton NMR of paramagnetic metal complexes: DANTE spin echoes for selective excitation in inhomogeneously broadened lines

Geoffrey Bodenhausen, Diego Carnevale, Gerald Bauer, Angel Joaquin Perez Linde

The paramagnetic complex bis(oxazolinylphenyl)amine-Fe(III)Cl-2 is investigated by means of solid-state proton NMR at 18.8 T (800 MHz) using magic-angle spinning at 65 kHz. Spin echoes that are excited and refocused by combs of rotor-synchronized pulses in ...
