Bis[cyclic (alkyl)(amino)carbene] isomers: Stable trans -bis(CAAC) versus facile olefin formation for cis -bis(CAAC)

2022

A trans-bis(CAAC) was isolated and shown to be a ditopic ligand for rhodium and iridium. The cis-isomer is unstable towards intramolecular CC-bond formation, however, its formal insertion products into the bonds of H2O and NH3 were identified.

Side‐on Coordination in Isostructural Nitrous Oxide and Carbon Dioxide Complexes of Nickel

2021

Abstract A nickel complex incorporating an N2O ligand with a rare η2‐N,N′‐coordination mode was isolated and characterized by X‐ray crystallography, as well as by IR and solid‐state NMR spectroscopy augmented by 15N‐labeling experiments. The isoelectronic nickel CO2 complex reported for comparison features a very similar solid‐state structure. Computational studies revealed that η2‐N2O binds to nickel slightly stronger than η2‐CO2 in this case, and comparably to or slightly stronger than η2‐CO2 to transition metals in general. Comparable transition‐state energies for the formation of isomeric η2‐N,N′‐ and η2‐N,O‐complexes, and a negligible activation barrier for the decomposition of the lat…

Bis[cyclic (alkyl)(amino)carbene] isomers : Stable trans-bis(CAAC) versus facile olefin formation for cis-bis(CAAC)

2022

Isomeric bis(aldiminium) salts with a 1,4-cyclohexylene framework were synthesized. The first isolable bis(CAAC) was prepared from the trans-stereoisomer and its ditopic ligand competency was proven by conversion to iridium(I) and rhodium(I) complexes. Upon deprotonation, the cis-isomer yielded an electron rich olefin via a classic, proton-catalyzed pathway. The C[double bond, length as m-dash]C bond formation from the desired cis-bis(CAAC) was shown to be thermodynamically very favorable and to involve a small activation barrier. Compounds that can be described as insertion products of the cis-bis(CAAC) into the E–H bonds of NH3, CH3CN and H2O were also identified. peerReviewed
