Abstract:
The catalyst system consisting of lithium N-phenylsydnone-4-carboxylate/Pd(PPh3)4 has proven to be an effective catalyst for the Suzuki–Miyaura reaction of 2,4-dinitrochlorobenzene with boronic acids in acetic acid at pH 5.7, whereas the N-phenylsydnone carbene palladium complex [sydPd(PPh3)2Br] required pH 8.0.

Abstract:
AbstractThe anion of N-phenylsydnone, which can be generated on treatment of N-phenylsydnone with cyanomethyllithium without decomposition, can be represented as tripolar zwitterionic and as anionic N-heterocyclic carbene resonance forms. Its palladium complex was prepared from 4-bromo-3-phenylsydnone and tetrakis(triphenylphosphine)palladium and proved to be active as catalyst in Suzuki-Miyaura reactions. Thus, 2,5-dibromo-3,4-dinitrothiophene was effectively converted into 2,5-diaryl-3,4-dinitrothiophenes with 1-naphthyl, (4-trifluoromethoxy)phenyl, [4-(methylsulfanyl)phenyl], and biphenyl-4

Abstract:
Suzuki–Miyaura reactions with Pd(PPh3)4 have been carried out using lithium N-phenylsydnone-4-carboxylate as additive, which gave best yields at pH 5.7 in a mixture of acetic acid, water, and sodium carbonate. Reaction parameters such as the Pd source, the solvent, reaction time and temperature, acid, base and carboxylate have been varied and some representative examples of the Suzuki–Miyaura reaction have been examined.

Abstract:
Sydnones are a class of mesoionic compounds containing a five-membered heterocyclic ring. In general, sydnone compounds are synthesized with an aromatic substutuent at the N3position. This feature, adds to the stability of the heterocyclic ring. In the title compound {systematic name: 4-(2-bromopropanoyl)-3-phenyl-1,2,3λ5-oxadiazol-3-ylium-5-olate}, C11H9BrN2O3, the aromatic substitutent is an unsubstituted phenyl ring. The sydnone ring is almost planar, with a maximum deviation from the mean plane of 0.023 (1) Å, but is not coplanar with the phenyl ring, having a dihedral angle of 40.93 (8)°.

Abstract:
碩士<br>靜宜大學<br>應用化學系<br>99<br>Sydnone is a typical mesoionic compound. Their unique dual properties have drawn some attention from a number of organic chemists. In this work, 3-aryl-4-phenlsydnones were prepared for nitration to demonstrate their dual properties. In general, the nitro group preferential substituted at C(4) position. However, with presence of an electron-donor on the benzene ring on N(3), the nitration will take place at both phenyl rings. The activation of benzene ring by methoxyl group is able to compensate the electro-withdrawing ability of the sydnone ring. In general,
