Ligand‐Controlled Chemoselectivity in the Rhodium‐Catalyzed Synthesis of Pentafulvenes via (2 + 2 + 1) Alkyne Cyclotrimerization

open access: yesAngewandte Chemie, EarlyView.
Chemoselectivity Challenge: A precise catalyst design allows for chemoselectivity control over alkyne reactivity to yield pentafulvenes via (2 + 2 + 1) cyclotrimerization. Operative mechanism has been elucidated by means of stoichiometric and deuteration experiments, as well as DFT calculations.

Opportunity observation of an Algerian Eddy to the south of Cape Palos (southwestern Mediterranean Sea)

open access: yesScientia Marina, 2023
Large anticyclonic eddies can detach from the Algerian Current, forming open-sea Algerian Eddies. These mesoscale structures have been intensively studied by means of sea surface temperature and altimetry data, and using numerical models.
