Benzylation and allylation of aldehyde acyl anions were enabled by the merger of a thiazolium N-heterocyclic carbene (NHC) catalyst and a palladium/bisphosphine catalyst in a synergistic manner. Owing to the mildness of the reaction conditions, various functional groups were tolerated in the substrates.

Dehydrative allylation between widely available aldehydes and allylic alcohols to afford β,γ‐unsaturated ketones was enabled by a synergistic merger of a thiazolium N‐heterocyclic carbene catalyst and a palladium‐bisphosphine catalyst.

Benzylation and allylation of aldehyde acyl anions were enabled by the merger of at hiazolium N-heterocyclic carbene (NHC) catalyst and apalladium/bisphosphine catalyst in asynergistic manner.Owing to the mildness of the reaction conditions,v arious functional groups were tolerated in the substrates.

Invited for the cover of this issue is the group of Hirohisa Ohmiya and co‐workers at Kanazawa University. The image depicts cooperative action between a thiazolium N‐heterocyclic carbene organocatalyst and a palladium catalyst. Read the full text of the article at https://doi.org/10.1002/chem.201805955.

Synergistic cooperation of thiazolium N‐heterocyclic carbene catalyst and a palladium catalyst enabled the dehydrative direct allylation between aldehydes and allylic alcohols to produce β,γ‐unsaturated ketones. The cover picture depicts a similar relationship between anemone fish and sea anemone living cooperatively in their natural environment. More information can be found in the Communication by H. Ohmiya et al. on page 724.
