Herein, we present a novel methodology that utilizes methanol as a\u00a0coreactant, with the goal of achieving high\u2010yield synthesis of polysubstituted alkylbenzenes. Under mild reaction conditions (280\u00a0\u00b0C), the process attains a 97.8% conversion rate of low\u2010density polyethylene (LDPE,\n                    <jats:italic>M<\/jats:italic>\n                    <jats:sub>w<\/jats:sub>\n                    \u00a0=\u00a0300\u00a0kDa) and complete conversion of methanol.

This mechanism steers the methylative homologation pathway toward the formation of polymethylated aromatics.
