2,3-Bis(phenoxymethyl)buta-1,3-diene
نویسندگان
چکیده
The mol-ecule of the title compound, C(18)H(18)O(2), a symmetrically phenol-substituted divinyl analog, exhibits crystallographically imposed C(2) symmetry. The phenolic and divinyl planar groups inter-sect each other orthogonally, with a dihedral angle of 82.7 (1)°. The structure is stabilized by a short intra-molecular C-H⋯O contact. The mol-ecules are held together by C-H⋯π inter-actions, forming a sheet structure parallel to the (201) plane.

A novel cyclization reaction between 2,3-bis(trimethylsilyl)buta-1,3-diene and acyl chlorides with straightforward formation of polysubstituted furans.
A novel cyclization process of 2,3-bis(trimethylsilyl)buta-1,3-diene with various acyl chlorides in the presence of aluminium trichloride affords 2,5-disubstituted or 2,3,5-trisubstituted furans in short reaction time; a subsequent acylation process of the furan ring occurs if the reaction time is prolonged.

The mol-ecule of the title compound, C(20)H(22)O(2), a symmetrically 2-methyl-phenol-substituted divinyl analog, exhibits crystallographically imposed C(2) symmetry. The mol-ecular structure is essentially planar. The structure is stabilized by a short inter-molecular C-H⋯O contact. Cooperative C-H⋯π inter-actions generate an infinite one-dimensional chain of mol-ecules along the a axis.

In the title compound, C(29)H(25)NS(2), both the Cl atoms of the aza-diene precursor 4,4-dichloro-1,1-diphenyl-2-aza-buta-1,3-diene are replaced by two vicinal S-p-tolyl substituents attached to the terminal C atom of a π-conjugated 2-aza-butadiene array. The aza-diene chain is planar to within 0.01 Å. One of the phenyl rings seems to be slightly π-conjugated with the aza-diene core [dihedral a...
متن کاملA novel 3,4-bis(sulfenyl)- or 4-selenenyl-3-sulfenylpenta-2,4-dienylation of aldehydes using 4-ethoxy-1,2-bis(sulfenyl)- or 1-Selenenyl-2-sulfenyl-buta-1,3-dienyl lithiums.
3,4-Dichalcogenopenta-2,4-dienylation of aldehydes proceeded in good to high yields using 4-ethoxy-1-(benzenesulfenyl)-2-(methanesulfenyl)- (5), 4-ethoxy-1,2-bis(benzenesulfenyl)but-1,3-diene (6), and 1-selenenyl derivatives 7 and 8. This novel four-carbon homologation could be applied to a synthesis of 3,4,7,8-tetrakis(benzenesulfenyl)-10,10-dimethylundeca-2,4,6,8-tetraenal (20).
متن کاملAn ab initio/RRKM study of product branching ratios in the photodissociation of buta-1,2- and -1,3-dienes and but-2-yne at 193 nm.
Ab initio G2M(MP2)//B3LYP/6-311G** calculations have been performed to investigate the reaction mechanism of photodissociation of buta-1,2- and -1,3-dienes and but-2-yne after their internal conversion into the vibrationally hot ground electronic state. The detailed study of the potential-energy surface was followed by microcanonical RRKM calculations of energy-dependent rate constants for indi...
