Synthesis and application of diphenyl sulfide linked bis(imidazoline) ligands: Dramatic electronic effect of ligands on catalytic behavior

Diphenyl sulfide linked bis(imidazoline) ligands with electron-withdrawing N-Ts substitution and electron-donating N-alkyl or N-H substitutions were synthesized through different routes. The electronic effects of the ligands were tuned rationally, and dra

Rational tuning of the rigidity of a ligand scaffold: synthesis of diphenylsulfide-linked bis(oxazoline) ligands and their application in asymmetric allylic alkylation

The scaffold rigidity of bis(oxazoline) ligands was rationally tuned on the basis of literature information. Diphenylsulfide-linked bis(oxazoline) ligands with a flexible scaffold were efficiently synthesized to test our hypothesis. The improved enantioselectivity in palladium-catalyzed asymmetric allylic alkylation reaction was achieved as we expected.

Spiro-λ4-sulfanes with intramolecular sulfur-oxygen interactions: Syntheses and molecular structures

Three novel N-acetylated spiro-λ4-sulfanes with five-membered spirorings (fused with aromatic rings) and with two N heteroatoms (in (1)) or with N and O heteroatoms (in (2) and (3)) in axial positions have been prepared and their molecular structures determined by X-ray diffraction. The molecular structures of compounds (1-3) show trigonal bipyramidal geometry about the central sulfur atom. The rather long axial S-N bonds(1.93 A)in he symmetric spiro-λ4-sulfane (1) exhibit the usual hypervalent character, whereas the S-N (1.73 and 1.80 A) and S-O (2.23 and 2.07 A) bond lengths in the unsymmetric spiro λ4-sulfanes (2) and (3) correspond to elongated covalent S-N bonds and highly polarized S-O hypervalent bonds, respectively. Each structure exhibits usual S-C(ar) bond lengths (1.79-1.81 A). The axial N-S-N/O and the equatorial C(ar)-S-C(ar) angles lie in the intervals 173-179°and 98-103°, respectively. The conformations of (1-3) including the single-cis-single-trans isomerism of the endocyclic and exocyclic amide parts, the shape of the spirorings, and the relative positions of the equatorial aromatic rings are discussed in detail. In (1-3) the exocyclic carbonyl-oxygen approaches the central sulfur atom by 2.90,2.73 and 2.71 A, respectively, leading to an effective intramolecular sulfur-oxygen interaction of 1,4-type. The S···O close contacts, however, do not alter appreciably the trigonal bipyramidal geometry about the central sulfur atom.

Synthesis and Properties of Achiral Coronands Incorporating the Sulfide and Sulfoxide Functionality

A number of polyether coronands incorporating sulfide and sulfoxide functionality and five or six ether oxygen atoms were prepared, their formation of complexes with alkali metal and ammonium salts were studied and the results were compared with analogous

Dibenzocyclooctene-, Dibenzochalcocine-, and Diarenochalconinediones

2,2'-Oxybis-, -thiobis-, and -methylenebisbenzoic esters 2a-c react with methyllithium in ether to give low yields of 5H-dibenzochalcocine-5,7(6H)-diones 6a, 7a, and dibenzocyclooctene-5,7(6H,12H)-dione (8), respectively.Very good yields of such heterocycles with oxygen (6a-h, 37), sulfur (7a-h, 38) and selenium (36) as key atom are obtained when diaryl ethers (21, 22, 25), -sulfides (27, 29, 30), and -selenides (33) that contain 2'-acetyl- (or -propionyl-) and 2-methoxycarbonyl groups are treated with sodium hydride in boiling toluene.Analogously are prepared the dibenzoxonine-11,13(6H,12H)diones 62a-c and 7H-benzonaphthothionine-7,9-(8H)-dione (65) which are expanded by one ring member.In the analogous reaction of a corresponding benzophenone derivative 35, spiro-3(2H),3'-dione (41) is formed in a tandem reaction. - Under phase transfer conditions the dibenzochalcocinediones 6, 7, 36 and also the corresponding nitrogen cycles 5 react to give mixtures of C- (42-45) and O-alkyl derivatives (46-49).Methyllithium and diisobutylaluminium hydride provide the carbinols 50-54.With bromine and SO2Cl2, respectively, the methylene group is mono- or dihalogenated to the products 56, 57; defined nitration was only possible for the oxacycle 6a.
