Estratégias para estudo das correla？？es de energia livre em acoplamento aril-aril de Suzuki: elucidando ciclos catalíticos através da equa？？o de Hammett

the present work deals with the study of the correlation of free-energy developed in a catalytic system for suzuki coupling, by way of the hammett equation. the system presents ncp pincer palladacycle 1 as a catalyst precursor, which proved to be very efficient in the coupling of various aryl boronic acids with aryl halides in previous studies. thus, the article presented here intends to serve as a support for further investigations and clarifications relating to cross-coupling catalytic cycles.
