DFT investigation of the 1-octene metathesis reaction mechanism with the Phobcat precatalyst
, 2009 The productive self-metathesis reaction of 1-octene in the presence of the Phobcat precatalyst [RuCl2(Phoban-Cy)2(=CHPh)] using density functional theory was investigated and compared to the Grubbs 1 precatalyst [RuCl2(PCy3)2(=CHPh)]. At the GGA-PW91/DNP

Autocatalytic Double sigma-Bond C(sp2)–N Transamination Metathesis Reaction
, 2022 The transamination reaction, which involves the conversion of one amine to another, traditionally relies on biological enzyme catalysts. Although chemists have recently developed few catalytic methods, mimicking these enzymes to interconvert amine groups

Angewandte Chemie International Edition, EarlyView.In many Pd‐catalyzed cross‐couplings, catalyst performance has been found to be limited by catalyst activation. Methylnaphthyl (MeNAP) palladium trifluoroacetate dimers are presented as easy‐to‐store and easy‐to‐handle precursors, which rapidly activate under reaction conditions, even when only weakly coordinating, non‐reducing nucleophiles are present.

Photogenerated Oxetanes as a Gateway to Uphill Cyclopropanation
Angewandte Chemie International Edition, EarlyView.An atom‐economical route to densely functionalized cyclopropanes from furans and photochemically activated aldehydes is enabled by a unique oxetane‐to‐cyclopropane rearrangement. These cyclopropanes can be used to access complex bioactive scaffolds and serve as a platform for asymmetric cyclopropane synthesis.
