Rhodium(I)-Complexes Catalyzed 1,4-Conjugate Addition of Arylzinc Chlorides to N-Boc-4-pyridone.
Rhodium(I)-complexes catalyzed the 1,4-conjugate addition of arylzinc chlorides to N-Boc-4-pyridone in the presence of chlorotrimethylsilane (TMSCl). A combination of [RhCl(C₂H₄)₂]₂ and BINAP was determined to be the most effective catalyst to promote the 1,4-conjugate addition reactions of arylzinc chlorides to N-Boc-4-pyridone. A broad scope of arylzinc reagents with both electron-withdrawing...
متن کاملN,N′-Bis[2-(methoxycarbonyl)ethyl]ethane-1,2-diammonium dichloride
In the crystal structure of the title compound, C(10)H(22)N(2)O(4) (2+)·2Cl(-) or (H(2)Me(2)eddp)Cl(2) (H(2)Me(2)eddp(2+) is the dimethyl N,N'-di-3-propane-carboxylato-ethane-1,2-diyldiimin-ium cation), the packing is stabilized by an infinite two-dimensional ⋯Cl⋯H-N-H⋯Cl⋯ hydrogen-bonding network. In addition, short C-H⋯Cl contacts are observed.

متن کاملN-(3-Bromo-1,4-dioxo-1,4-dihydro-2-naphthyl)-4-fluoro-N-(4-fluorobenzoyl)benzamide
In the title compound, C(24)H(12)BrF(2)NO(4), synthesized from 2-amino-3-bromo-1,4-naphthoquinone and 4-fluoro-benzoyl chloride, the two p-fluoro-phenyl rings are inclined at 73.9 (1) and 73.6 (1)° to the naphthoquinone ring system. The two imido carbonyl O atoms are anti to each other, while the fluoro-phenyl rings are located opposite each other, connected to the imide group in a funnel-like ...

In the title compound, C(19)H(12)Cl(2)N(2)O(5)S(3), the benzene rings of the chloro-phenyl-sulfonyl groups form a dihedral angle of 35.85 (8)° and are inclined at angles of 23.51 (6) and 59.22 (6)° with respect to the essentially planar benzisothia-zole ring system [maximum deviation = 0.030 (2) Å]. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond. In the crys...
