The synthesis of [H2C(PPh2=NSiMe3)(SO2Ph)] (1) and its mono- and dimetalation are reported. Due to the strong anion-stabilizing abilities of the iminophosphoryl and the sulfonyl group monometalation to 1-K and dimetalation to 1-Li2 proceed smoothly w

Alkali metal amides are highly reactive reagents that are broadly applied as strong bases in organic synthesis. Here, we use a combined helium nanodroplet IR spectroscopic and theoretical (DFT calculation) study to show that the reaction of the model

The use of iminophosphoryl-tethered ruthenium carbene complexes for activation of secondary phosphine P-H bonds is reported. Complexes of type [(p-cymene)-RuC(SO 2 Ph)(PPh 2 NR)] (with R = SiMe 3 or 4-C 6 H 4 -NO 2 ) were found to exhibit different r

Ylide-substituted phosphines (YPhos) have been shown to be highly electron-rich and efficient ligands in a variety of palladium catalyzed transformations. Here, the synthesis and characterization of novel YPhos ligands containing a cyclic backbone ar

A new PCcarbeneS ligand has been designed to stabilize late transition metal carbene complexes with Schrock-type reactivity for bond activations via metal–ligand cooperation. This ligand combines previous approaches to such complexes by stabilizing

The α‐metallated ylides [Ph3P−C−Z]−M+ (with Z=SO2Tol or CN and M=Na or K) were used as versatile nucleophiles for the facile access to ylide‐substituted compounds. Halogenations, alkylations, carbonylations and functionalization reactions
