PdI2‑Catalyzed Regioselective Cyclocarbonylation of 2‑Allyl Phenols to Dihydrocoumarins

A simple, efficient, and regioselective synthesis of 3-methyl-3,4-dihydro­coumarins is reported. The reaction of 2-allyl phenols with synthesis gas was catalyzed by PdI2, and 1,3,5,7-tetra­methyl-6-phenyl-2,4,8-trioxa-6-phos­pha­adaman­tane (L1) and 1,3,5,7-tetra­methyl-6-tetra­decyl-2,4,8-trioxa-6-...
