3-Bromo-5-tert-butyl-2-hydroxybenzaldehyde
The mol-ecular conformation of the title compound, C(11)H(13)BrO(2), is stabilized by an intra-molecular O-H⋯O hydrogen bond. All non-H atoms except the methyl groups lie approximately in a common plane (r.m.s. deviation = 0.011 Å).
متن کاملCrystal structure of 2,4-di-tert-butyl-6-(hydroxymethyl)phenol
The title compound, C15H24O2, is an example of a phenol-based pendant-arm precursor. In the mol-ecule, the phenol hy-droxy group participates in an intra-molecular O-H⋯O hydrogen bond with the pendant alcohol group, forming an S(6) ring. This ring adopts a half-chair conformation. In the crystal, O-H⋯O hydrogen bonds connect mol-ecules related by the 31 screw axes, forming chains along the c ax...
متن کاملCrystal structure of tert-butyl-N-phenylcarbonitrilium tetrachloridoaluminate
In the title compound, (C11H14N)[AlCl4], the nitrilium (systematic name: 2,2-dimethyl-N-phenyl-propane-nitrilium) ion adopts a slightly distorted linear configuration [C-N C = 178.87 (16) and N C-C = 179.13 (17)°]. In the crystal, while there are no inter-molecular hydrogen bonds, pairs of nitrilium ions are linked through π-π inter-actions [inter-centroid distance = 3.8091 (13) Å].

The crystal and molecular structure of tert-butyl 4-(2-tert-butoxy-2-oxoethyl)piperazine-1-carboxylate is reported. The title compound crystallizes from a petroleum ether/ethyl acetate mixture in the monoclinic space group P 21/c with four molecules in the unit cell. The unit cell parameters are: a = 8.4007(2) Å, b = 16.4716(4) Å, c = 12.4876(3) Å; β = 90.948(1)° and V = 1727.71(7) Å. Bond leng...
متن کامل2 - ( tert - Butyl ) - 4 - phenyloxetane
The two geometric isomers of 2-(tert-butyl)-4-phenyloxetane have, for the first time, been prepared starting from the commercially available 4,4-dimethyl-1-phenylpentane-1,3-dione. The latter was reduced with NaBH4 to give a mixture of diastereomeric syn and anti diols which were then stereospecifically cyclized into the corresponding oxetanes with an overall yield for the two steps of 69.6%. T...
