Catalysis, irrespective of its form can be considered as one of the most important pillars of today’s chemical industry. The development of new catalysts with improved performances is therefore a highly strategic issue. However, the a priori theoretical design of the best catalyst for a desired reaction is not yet possible and a time- and money-consuming experimental phase is still needed to develop a new catalyst for a given reaction.

Knochel – Hauser bases, derived from 2,2,6,6-tetramethylpiperidinyl (TMP) metal amides, offer exceptional selectivity and functional group tolerance in the regioselective metalation of arenes and heteroarenes. The selectivity, stability and yield of these reactions are highly dependent on the nature of the base, additive and deprotonation temperature.

Reversible addition–fragmentation chain transfer (RAFT) copolymerization was used to prepare copolymers of N-isopropyl acrylamide (NIPAM) and vinyl acetate (VAc) with mole fractions of NIPAM ranging from 0.1 to 0.6 and targeted degrees of polymerization of 100 and 250. The measured kinetic parameters and obtained experimental results revealed that this copolymerization system leads to a “one pot” synthesis of amphiphilic gradient copolymers,

A series of dual pH- and ultrasound responsive statistical copolymers were synthesized via the reversible addition–fragmentation chain transfer (RAFT) polymerization of 3,4-dihydro-2H-pyran (DHP) protected HEMA 2-((tetrahydro-2H-pyran-2-yl)oxy)ethyl methacrylate (THP-HEMA) and 2-(dimethylamino)ethyl methacrylate (DMAEMA)

A systematic investigation to fine-tune the cloud point of thermoresponsive poly [2-(dimethylamino)ethyl methacrylate) (p(DMAEMA)) aqueous solutions in a broad temperature interval is reported. For this research, p(DMAEMA)s of different molar mass are quaternized at distinct degrees with methyl iodide to obtain an expanded library of poly[DMAEMA-copoly[ 2-(methacryloyloxy) ethyl] trimethylammonium iodide]s
