Electrocatalytic behavior of TEMPO derivative SAMs on gold has been studied in the presence of benzyl alcohol. The results demonstrate that interfacial activity of the SAMs can be enhanced by diluting the TEMPO moiety with an alkyl passive matrix. The absolute catalytic activity exhibits a maximum for an intermediate value of the surface coverage of catalytic centers. The most significant featu...

In the title 1,2,4-oxadiazole derivative, C(19)H(18)ClN(3)O(3), the 1,2,4-oxadiazole ring makes dihedral angles of 12.83 (8) and 4.89 (8)°, respectively, with the benzyl and 4-chloro-phenyl rings, while the dihedral angle between the benzyl and 4-chloro-phenyl rings is 11.53 (7)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into helical chains along the b axis. A weak C-H⋯π in...

The piperidine ring of the title compound, C(30)H(26)Cl(2)FN(3)O(2), adopts a twisted chair conformation. The pyrrolidine ring has a twisted envelope structure with the N atom at the flap [displaced by 0.592 (3) Å]. The fluoro-oxindole, chloro-phenyl and chloro-benzyl-idene groups are planar with r.m.s. deviations of 0.0348, 0.0048 and 0.0048 Å, respectively. The structure is stabilized by inte...

The mol-ecule of title compound, C(39)H(56)O(5), contains five fused six-membered rings, four of which (rings A, B, D and E) adopt a chair conformation, while the other (ring C) has a half chair conformation. The acet-oxy and carb-oxy-benzyl groups occupy equatorial positions.

Seven bis(pyrrolylaldiminato)aluminum methyl complexes were synthesized from the reactions of AlMe3 and two equiv. of the corresponding pyrrolylaldimine ligands. The ligands were modified to have different steric hindrances (C6H5 (1), 2,6-Me2C6H3 (2), 2,4,6-Me3C6H2 (3), 2,6-Et2C6H3 (4) and 2,6-(i)Pr2C6H3 (5)) and electronic contributions (4-CF3C6H4 (6) and 4-OMeC6H4 (7)). Crystal structures of ...

Reactions of primary and secondary benzylic chlorides with trifluoromethyltrimethylsilane in the presence of a catalytic amount of copper(i) thiophene-2-carboxylate (CuTC) have been found to give the corresponding benzylic trifluoromethylated products in good to high yields.

In the title compound, C(20)H(25)NO(2)S, the cyclo-hexyl ring exists in a chair form and the mean plane through all six atoms makes dihedral angles of 56.12 (9) and 55.19 (10)° with the benzene and phenyl rings, respectively. The dihedral angle between the two aromatic rings is 77.23 (7)°. A weak intra-molecular C-H⋯O interaction occurs.

The synthesis of dibenzyl-(1S*,2S*)-2,3-dihydro-1H-indene-1,2-dicarboxylate has been realized through a diastereospecific bis-alkoxycarbonylation reaction, which starts from the cheap and easily available 1H-indene, benzyl alcohol, carbon monoxide. catalyst is formed in situ by mixing Pd(TFA)2, ligand N2,N3-bis(2,6-dimethylphenyl)butane-2,3-diimine, p-benzoquinone used as an oxidant, alcohol ac...

The palladium catalytic system was first applied to 2-arylquinazoline synthesis via hydrogen transfer methodology. Various (E)-2-nitrobenzaldehyde O-methyl oximes reacted easily with alcohols or benzyl amines to provide N-heterocyclic compounds in good to high yields. Similarly, the heterocyclic products could be prepared by the reaction of 1-(2-nitrophenyl)ethanone, urea and benzyl alcohols. I...

A phenol-catalyzed aerobic oxidative styryl ether formation method was developed with benzyl alcohol under basic DMSO. Styryl ether was obtained after 12 hours of heating at 60-80 °C where DMSO was involved in the reaction as the extra carbon source. Control experiments indicated that both phenol and DMSO are crucial for the success of the reaction. A variety of styryl ethers were prepared smoo...
