In the title compound, C(17)H(14)O(6), the dihedral angle between the two anhydride rings is 76.01 (8)°while the dihedral angles between the benzene and anhydride rings are 42.60 (7) and 68.94 (7)°. The cyclo-hexene ring of the tetra-hydro-naphthalene unit exhibits an envelope conformation.

Mo and W MonoAryloxide-Pyrrolide (MAP) olefin metathesis catalysts can couple terminal olefins to give as high as >98% Z-products in moderate to high yields with as little as 0.2% catalyst. Results are reported for 1-hexene, 1-octene, allylbenzene, allyltrimethylsilane, methyl-10-undecenoate, methyl-9-decenoate, allylB(pinacolate), allylOBenzyl, allylNHTosyl, and allylNHPh. It is proposed that ...

The title compound, C(28)H(26)N(2)O(4), crystallizes as a racemate with four stereogenic centers. In the molecule, the pyrrolidone ring adopts an envelope conformation and the cyclo-hexene ring has a twisted envelope conformation. In the crystal structure, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds.

In the title compound, C(16)H(13)N(3), the cyclo-hexene ring adopts a sofa conformation. An intra-molecular N-H⋯N hydrogen bond generates an S(7) ring motif. In the crystal, the mol-ecules are linked by pairs of N-H⋯N inter-actions, forming centrosymmetric dimers with an R(2) (2)(14) motif.

In the quinoline fused-ring system of the title compound, C(9)H(9)NO, the pyridine ring is planar to within 0.011 (3) Å, while the partially saturated cyclo-hexene ring adopts a sofa conformation with an asymmetry parameter ΔC(s)(C6) = 1.5 (4)°. There are no classical hydrogen bonds in the crystal structure. Mol-ecules form mol-ecular layers parallel to (100) with a distance between the layers ...

This work presents the results of studying behavior catalytic systems formed on basis trichlorotris-(tetrahydrofuranate)chromium(III) in presence sulfur-containing tridentate SOS-type ligands and activated by various organoaluminum compounds. In formation systems, following compounds were used: - bis-(2-methylthioethyl) ether, bis-(2-ethylthioethyl) ether bis-(2-phenylthioethyl) triethylaluminu...

Self-assembly of miktoarm star-like ABn block copolymer in both selective solvent (A- or B-selective) and miscible homopolymer matrix (A or B homopolymer), that is, formation of micelles, was for the first time investigated by theoretical calculations based on self-consistent mean field theory. Interestingly, the calculation revealed that the size of micelles in solvent was smaller than that in...

An UCST-type copolymer of acrylamide (AAm) and acrylonitrile (AN) (poly(AAm-co-AN)) was prepared by reversible addition fragmentation chain transfer (RAFT) polymerization and its temperature-induced phase transition and aggregation behaviour studied by turbidimetry, static and dynamic light scattering, small angle neutron scattering (SANS) and cryo-transmission electron microscopy (cryo-TEM) me...

Present research is a preliminary report on the novel pH-responsive micelles based on an amphiphilic brush copolymer P(PEGMA)-b-P(DMAEMA-co-CPLAMA) used as the promising drug carrier. The copolymer was synthesized using cholesteryl poly(L-lactic acid) methacrylate (CPLAMA), poly(ethylene glycol) monomethyl ether methacrylate (PEGMA) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) with appropri...
