Synthesis and structural characterisation of the first N-heterocyclic carbene ligand fused to a porphyrin.

چکیده
The functionalisation of two neighboring beta-pyrrolic positions of a porphyrin by a fused N-heterocyclic carbene ligand, the subsequent metallation of this external coordination site by palladium(II) and the structural characterisation of the resulting compounds are presented.

متن کاملSynthesis and characterisation of an N-heterocyclic carbene with spatially-defined steric impact.
The synthesis and co-ordination chemistry of a new 'bulky yet flexible' N-heterocyclic carbene ("IPaul") is reported. This carbene has spatially-defined steric impact; steric maps show that two quadrants are very bulky while the other two are quite open. The electronic properties of this carbene are very similar to those of other 1,3-diarylimidazol-2-ylidenes. Copper, silver, iridium, and nicke...
