چکیده
The title compound, C(37)H(52)O(4)S, was obtained by the reaction of 6,6'-(ethane-1,1-di-yl)bis-(2,4-di-tert-butyl-phenol) and 4-methyl-benzene-1-sulfonyl chloride. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond. Two of the tert-butyl groups are disordered over two sets of sites with occupancies 0.530 (15)/0.470 (15) and 0.615 (11)/0.385 (11).

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...

The reaction of (η(3)-all-yl)[(1,2,5,6-η)-cyclo-octa-1,5-diene]rhodium(I) with tris-(2,4-di-tert-butyl-phen-yl)phosphite in toluene produces the title compound, [Rh(C(42)H(62)O(3)P)(C(8)H(12))]·C(7)H(8), by spontaneous metallation at one of the nonsubstituted phenyl ortho-C atoms of the phosphite mol-ecule. The coordination geometry at the Rh(I) ion is distorted square-planar. The toluene solve...

The angles within the benzene ring in the title compound, C(30)H(49)N(3)O, ranging from 116.34 (16) to 124.18 (16)°, reflect the presence of electron-donating and electron-withdrawing substituents. The angles at the two electron-donating tert-butyl substituents are smaller than 120°, at the electron-withdrawing eth-oxy substituent larger than 120°, and at the imine substituent equal to 119.59 (...
