Abstract

1H and 13C NMR chemical shifts have been determined and assigned based on PFG 1H, 13C HM⋯C, and HMBC experiments for 3-(4'-X-benzyl)-4-chromenones (Ia, X = CN and Ib, X = NO 2), 3-(4'-X-benzyl)-4-thiochromenones (IIa, X = Cl and IIb, X = Br), (E)-3-(4'-Xbenzylidene)- 4-chromanones (IIIa-IIIe, X = OCH 3, CH 3, Cl, N(CH 3) 2, Br), (Z)-3-(40-X-benzylidene)4- thiochromanones (IVa-IVd, X = Cl, Br, F, OCH3), 2-benzyl-1,2,3, 4-tetrahydro-1-naphthol (V), 2-benzyl- and (E)-2-benzylidene- 1-tetralones (VI and VII), and (E)-2-benzylidene-1- benzosuberol (VIII). The crystal structures have been determined for the following seven compounds: derivatives of 4-chromanones (IIIa-IIId), 1-tetrahydronaphtol (V), and 1-tetralones (VI and VII). The molecular features and intermolecular interactions in crystal state have been discussed.
