The reductive coupling of aromatic monocarbonyl compounds in the presence of SmI 2 results in the formation of Samarium(III) dialkoxides. These Sm(III) dialkoxides have been utilized as initiators for ring opening polymerization (ROP) of lactones and lactides. The reductive coupling of aromatic dicarbonyl compounds results in the formation of Sm(III) polyalkoxides which have been used as polyinitiator for (ROP) of lactones and lactides. The products of this process are poly(p‐xylylene)s grafted by polylactones or polylactides. Grafting efficiency depends significantly on reaction conditions and is currently limited to 28%.
