2,4-Di-tert-butyl-6-[(R/S)-1-(3,5-di-tert-butyl-2-hy-droxy-phen-yl)eth-yl]phenyl [(1R,4S)-7,7-dimethyl-2-oxobicyclo-[2.2.1]heptan-1-yl]methane-sulfonate.

ABSTRACT: 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-molecular O-H?O hydrogen bonds, whereas van der Waals inter-actions define the crystal packing.

(Biphenyl-2,2'-di-yl)di-tert-butyl-phos-phonium trifluoro-methane-sulfonate.

Project description:To aid in the elucidation of catalytic reaction mechanism of palladacycles, we found that reaction of trifluoro-methane-sulfonic acid with a phosphapalladacycle resulted in elimination of the palladium and formation of the title phospholium salt, C20H26P(+)·CF3SO3(-). Selected geometrical parameters include P-biphenyl (av.) = 1.801?(3)?Å and P-t-Bu (av.) = 1.858?(3)?Å, and significant distortion of the tetra-hedral P-atom environment with biphen-yl-P-biphenyl = 93.93?(13)° and t-Bu-P-t-Bu = 118.82?(14)°. In the crystal, weak C-H?O inter-actions lead to channels along the c axis that are occupied by CF3SO3(-) anions.

2,4-Di-tert-butyl-6-[1-(3,5-di-tert-butyl-2-hydroxy-phen-yl)eth-yl]phenyl 4-methyl-benzene-sulfonate.

Project description: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).

[(1R,4S)-(+)-3-Benzoyl-1,7,7-trimethyl-bicyclo-[2.2.1]heptan-2-olato-?O,O](?-norbornadiene)rhodium(I).

Project description:In the title complex mol-ecule, [Rh(C(17)H(19)O(2))(C(7)H(8))], the rhodium(I) metal centre is coordinated by the O atoms of a benzoyl-camphorate anion and the C=C bonds of the norbornadiene mol-ecule into a slightly distorted square-planar coordination geometry. The six-membered chelate ring is essentially planar (r.m.s. deviation = 0.0378?Å) and forms a dihedral angle of 31.67?(11)° with the phenyl ring.

Project description:In the title compound, C(30)H(38)O(4)S, the hydroxyl group bonded to one phenyl ring and an O atom of the benzene-sulfonate group attached to the other phenyl ring of the biphenyl backbone of the structure are involved in an intra-molecular O-H?O hydrogen bond.

(3,5-Di-tert-butyl-2-eth-oxy-benzyl-idene)[2-(3,5-di-tert-butyl-1H-pyrazol-1-yl)eth-yl]amine.

Project description: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 (16)°. The latter does not reflect the electron-donating nature of the imine group due to the presence of other substituents.

Di-n-butyl-ammonium 2-[(3,5-di-tert-butyl-4-hy-droxy-benz-yl)sulfan-yl]benzoate.

Project description:The title salt, C(8)H(20)N(+)·C(22)H(27)O(3)S(-), is a proton-transfer compound derived from the recently reported parent carb-oxy-lic acid [Alhadi et al. (2010). Acta Cryst. E66, o1787] by the addition of a second equivalent of di-n-butyl-amine, yielding the di-n-butyl-ammonium carboxyl-ate salt. The structure of the carboxyl-ate anion resembles that of the parent carb-oxy-lic acid. The main difference lies in the position of the H atom in the 4-hy-droxy group. In the anion the O-H bond is perpendicular, rather than parallel, to the benzyl ring. This position appears to facilitate hydrogen bonding to an O atom of the carboxyl-ate group of a symmetry-related anion. In addition, there are three N-H⋯O hydrogen bonds. In contrast, the neutral species hydrogen bonds via a carboxylic acid dimer. The dihedral angle between the benzene rings in the anion is 79.19 (7)°.

Di-n-butyl-ammonium 2-(3,5-di-tert-butyl-4-hydroxy-benzyl-sulfan-yl)nicotinate.

Project description:The asymmetric unit of the title compound, C(8)H(20)N(+)·C(21)H(26)NO(3)S(-), contains two indpendent ion pairs which are disposed about a psuedo-inversion center, generating an ammonium-carboxylate N-H?O hydrogen-bonded four-component cluster. In the crystal structure, adjacent clusters are linked by hydr-oxy-carboxylate O-H?O hydrogen bonds, forming a chain.
