The aza-Michael reaction as an alternative strategy to generate advanced silicon-based (macro)molecules and materials

摘要: Abstract Aza-Michael reaction is a simple and accessible addition performed at moderate temperature, possibly without catalyst releasing by-products. Its versatility allows designing specific structures thanks to the availability of multitude Michael acceptors donors. The rate aza-Michael can be improved by adding different co-reactants (polar protic solvents, catalysts) and/or adjusting external energy sources (e.g. high temperatures or pressures). Here, we show that this efficient for modifying curing silicon-containing molecules, oligomers polymers. pros cons applying molecules (including alkoxysilanes PDMS) are highlighted. A large variety intermediates such as coupling agents, reactive diluents, sol-gel precursors prepared presented. Finally, applications these, including products ranging from functional silicone soft (unfilled) elastomers, reported.
