The asymmetric unit of the title compound, C(40)H(60)O(5)S, comprises two diastereomers related, except for the chiral camphor groups, by a pseudo-inversion centre. In both diasteromers, the camphor sulfate moiety maintained the absolute configuartion (R,S) of the precursor. However, the absolute configurations at the methine C atoms are of opposite chirality. Both mol-ecules reveal intra-molec...

In the title compound, C(15)H(14)O(3)S, the dihedral angle between the two benzene rings is 59.3 (8)°. The crystal structure is stabilized by weak inter-molecular C-H⋯π inter-actions between the benzene rings and the central ethyl-ene bridge, and a weak non-classical C-H⋯O hydrogen bond occurs in the structure.

Treatment of 4-heptafluoroisopropyl-2-methoxy-3,5,6-trifluropyridine (4 ) with aqueous ammonia in THF gave 2-amino-3,5-difluoro-4-heptafluoroisopropyl- 6-methoxy pyridine (5) in 7 1% yield. Chlorination of this amine with 'ButOCl at -16°C gave an unstable product, namely 2-dichloroarnino-3,5- difluoro-4-heptafluoroisopropyl-6-methoxy pyridine (6). Iodine-catalysed rearrangement of this dic...
