Titolo: The chemistry of DMC: from laboratory reactions to its application to the conservation of Cultural Heritage

Abstract:
The worldwide urge to embrace a sustainable and bio-compatible chemistry has led industry and academia to the development of chlorine-free methodologies focused on the use of CO2 and CO2-based compounds as feedstocks, promoters and reaction media. In this scenario, dialkyl carbonates (DACs) and in particular dimethyl carbonate (DMC) occupy a privileged position due to their low-toxicity, high biodegradability and peculiar reactivity. Nowadays the large-scale production of DMC is carried out through clean processes (i.e., phosgene-free processes). This groundbreaking achievement has definitely drawn the attention toward the conception of procedures to activate the rather stable DACs, with the aim to employ these compounds as green alternative to their reactive chlorinated analogues. DACs are ambident electrophiles, which under appropriate conditions can undergo BAc2- or BAl2- nucleophilic substitution to give respectively alkoxycarbonylation and alkylation reaction. Surprisingly, the many efforts devoted to improve the industrial suitability of organic carbonates as reagents and solvents have unveiled an intriguing and innovative chemistry as demonstrated by the ever increasing number of publications and patents published over the last thirty years.
