Temi di ricerca

L’aromaticità è un concetto che ha affascinato i chimici di tutto il mondo negli ultimi due secoli, permettendo di descrivere e predire le proprietà di una vastissima gamma di molecole. Sebbene le molecole aromatiche mostrino una varietà incredibile di strutture e applicazioni, solo pochi atomi della tavola periodica sono utilizzati per la loro costruzione, principalmente H, C, N e O. Il gruppo di ricerca è uno dei pochissimi al mondo che studia sperimentalmente le proprietà dell’aromaticità metallica, in cui nuclei di metalli di transizione mimano il comportamento dei tradizionali composti organici. Grazie al sostegno del progetto SIR AROMA-TRIP, è stata estesa la possibilità di ottenere complessi aromatici incorporando palladio, platino e rutenio.

L’aromaticità metallica studia particolari architetture molecolari che mimano il comportamento e i legami chimici delocalizzati delle tradizionali molecole organiche aromatiche, incorporando invece nuclei di metalli di transizione. Le applicazioni di questi complessi sono tuttavia limitatissime, a causa della generale difficoltà nella sintesi di queste molecole. Grazie al sostegno del progetto SIR AROMA-TRIP, è stata messa a punto una semplice via sintetica che permette di ottenere una famiglia di complessi metallo-aromatici trinucleari incorporando palladio, platino e più recentemente rutenio. Le prove preliminari sulle proprietà catalitiche dei complessi di palladio hanno già permesso lo sviluppo di nuove metodologie sintetiche, alternative ai tradizionali catalizzatori mononucleari. In particolare, è stato sviluppato un sistema catalitico sicuro ed incredibilmente efficiente, in termini di robustezza, selettività e parametri ambientali per la semiriduzione di alchini. Inoltre è stato possibile sfruttare per la prima volta un cluster nella formazione selettiva di legami carbonio-carbonio. La particolare stabilità chimica di questi complessi, dovuta alla loro aromaticità, li rende infine specie ibride che possono accomunare i vantaggi sia dei catalizzatori omogenei, quali il controllo a livello atomico delle caratteristiche strutturali, sia di quelli eterogenei, quali la robustezza chimica per svariate migliaia di turnover.

Più di recente, esperimenti preliminari hanno mostrato reattività inattese utilizzando gli omologhi complessi trinucleari di platino. Questi permettono di portare la formazione di architetture molecolari complesse, quali le tetraidropiridine bicicliche che si incontrano ad esempio in numerosi farmaci e prodotti naturali aventi proprietà biologiche.

Altri progetti in corso ruotano intorno a vari aspetti poco consciuti della catalisi con complessi di palladio ed all'uso della luce visibile per reazioni in cascata.
