2,4,6-Tris(4-fluorophenyl)-2-(1-pyridyl)-boroxine
Crystals of the title compound, C(23)H(17)B(3)F(3)NO(3), were obtained unintentionally by slow evaporation of a chloro-form solution of the preformed boroxine-pyridine adduct. The mol-ecule contains three fluoro-substituted benzene rings, each bonded to one of the three B atoms of a six-membered boroxine ring. A pyridyl ring is also bound to one of the B atoms through a Lewis acid-base inter-ac...
متن کاملSynthesis and Properties of 2-(2-Pyridyl)-1-azaazulene
The title azaazulene 3 was synthesized either by reaction of tropone with N-{(2-pyridyl)acetyl}pyridinium iodide in the presence of ammonium acetate or by palladium-catalyzed cross-couplings between 2-halo-1-azaazulene and 2-substituted pyridine. The compound shows relatively stronger basicity compared with 2,2’-bipyridyl. While 3 showed no emission from the S1 state but from the S2 state like ...
متن کاملDi-2-pyridyl disulfide–succinic acid (1/1)
In the title compound, C(10)H(8)N(2)S(2)·C(4)H(6)O(2), both components of the cocrystal lie on crystallographic twofold rotation axes. In the di-2-pyridyl disulfide mol-ecule, the dihedral angle between the two pyridine rings is 66.6 (1)°. In the crystal structure, inter-molecular O-H⋯N and weak C-H⋯O hydrogen bonds link both types of mol-ecules into columns along the c axis.
متن کامل1-Nitro-2,3-di-2-pyridyl-2,3-dihydroindolizine
The title compound, C(18)H(14)N(4)O(2), was found as a by-product in the nitro-aldol reaction between 2-(nitro-meth-yl)pyridine and N-(pyridin-2-ylmethyl-idene)methane-amine. Its two stereogenic centers give rise to four stereoisomers of which only the anti isomers are found in this crystal structure.
متن کامل1,2-Diphenyl-2-[4-(4-pyridyl)benzylidenehydrazono]ethan-1-one
In the title compound, C(26)H(19)N(3)O, the dimethyl-ene hydrazine (-C=N-N=C-) unit is approximately planar, the torsion angle around the N-N bond being 162.2 (6)°. The phenyl and benzoyl-phenyl rings at one end of the hydrazine unit are aligned at angles of 9.5 (5) and 88.5 (4)°, respectively, with respect to the hydrazine unit, whereas the benzene ring at the other end is twisted by an angle ...
