The 13 C NMR assignments for 35 substituted 2,2‐dimethyl‐2H‐chromene derivatives are reported. These include methyl, tert ‐butyl, chloro, nitro, methoxy, ethoxy, n‐propyloxy, isopropyloxy, n‐butyloxy, sec‐butyloxy, isobutyloxy, cyclopentyloxy, benzyloxy and prop‐2‐ynyloxy groups as substituents on the aromatic ring.
