Abstract: PMR detn. of vicinal coupling consts. and Eu-reagent shifts showed the conformation of trans-2,3-dichlorotetrahydro-furan to be diaxial with the C(3) and C(4) carbons puckered above and below the C(5)-O-C(2) plane, resp. Population of favored conformers was calcd. from pseudorotational barriers.
