It has also been noted that polar aprotic solvents can promote activity. These reactions are thought to be fast relative to competing radical polymerization. Suddaby et al.58 described the effect of CTAs in N′,N-dimethyl formamide (DMF) as catalytic inhibition. DMF forms a complex with the ...
Participatory: as a source ofacid(proton),base(removing protons), or as anucleophile(donating a lone pair of electrons). The only class of solvents for which this is something you generally need to worry about are polar protic solvents (see below). 2. Polar Solvents Have Large Dipole Moment...
