5-(Diphenylmethylidene)pyrrolidin-2-one
In the title compound, C(17)H(15)NO, the dihedral angle between the phenyl rings is 80.1 (2)°. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers.

In the title 1,3,2-dioxaphospho-rinane derivative, C(10)H(11)Br(2)O(4)P, the 1,3,2-dioxaphospho-rinane ring adopts a chair conformation, having the P=O bond equatorially oriented and the phen-oxy group axially oriented. The bromo substituent is in an axial position opposite to the phen-oxy group and the bromo-methyl group is in an equatorial position opposite to the P=O bond. In the crystal pac...

In the title compound, C(11)H(9)BrN(2)O, the mol-ecules are linked into R(2) (2)(8) dimers by paired N-H⋯O hydrogen bonds and these dimers are further stacked into columns along the c axis by π-π inter-actions between pyrazinone rings [centroid-centroid distance = 3.544 Å; the dihedral angle between the planes of these rings is 7.51 (16)°]. The title compound is a precursor for agents with pote...

The title chalcone (E)-1-(2-aminophenyl)-3-(benzo[d][1,3]dioxol-5-yl)prop-2-en-1-one was obtained in 76% yield from a NaOH catalyzed Claisen–Schmidt condensation reaction between o-aminoacetophenone and piperonal. This product will be used as a key precursor for the development of an alternative route for the total synthesis of the alkaloid Graveoline. Single crystals of the title compound suit...
متن کامل5-Nitro-1-benzofuran-2(3H)-one
In the crystal structure of the title compound, C(8)H(5)NO(4), essentially planar mol-ecules [largest deviation from the least-squares plane = 0.030 (2) Å] form stacks along the a-axis direction. Intercentroid separations between overlapping benzene rings within the stack are 3.6594 (12) Å and 3.8131 (12) Å. Mol-ecules from neighboring stacks are linked by weak C-H⋯O hydrogen bonds into inversi...
