Non-Abelian Hadamard Difference Sets
Difference sets wi th pa rame te r s (v, k, 2) m a y exist even if there are no abelian (v, k, ,~) difference sets; we give the first k n o w n example of this s i tuat ion. This example gives rise to an infinite family of non -abe l i an difference sets w i th pa rameters (4t 2, 2t a t, t 2 t), where t = 2 q. 3 r5 . 1 0 ' , q, r, s >/0, and r > 0 ~ q > 0. N o abel ian difference sets w i th th...

Reaction of readily available 2-formyl -1-methyl-5-nitroimidazole (1) with 4-substituted-2-hydrazinothiazoles (2) afforded 2-formyl-l-methyl-5- nitroimidazole 4-substituted -2- thiazolylhydrazones (3). Reaction of thiochromitn-4-one (4) with thiosemicarbazide gave thiochroman-4- one thiosemicarbazone (5). Reaction of compound 5 with clc- haloaldehyde or ketones y ielded thiochroman--#-one ...
متن کامل1-Formyl-r-2,c-6-bis(4-methoxyphenyl)-t-3,t-5-dimethylpiperidin-4-one
In the title compound, C(22)H(25)NO(4), the piperidine ring adopts a distorted boat conformation. The methyl groups at the 3 and 5 positions of the piperidine ring are in axial and equatorial orientations, respectively. Both H and O atoms in the aldehyde group are disordered over two positions with occupancies of 0.534 (5) and 0.466 (5). In the crystal, the mol-ecules are linked into a three-di...
متن کامل1-Dichloroacetyl-r-2,c-6-bis(4-methoxyphenyl)-t-3,t-5-dimethylpiperidin-4-one
In the title compound, C(23)H(25)Cl(2)NO(4), the piperidine ring adopts a distorted boat conformation. The dihedral angle between the benzene rings is 54.8 (1)°. In the crystal, the mol-ecules are linked into a two-dimensional network parallel to the ab plane by C-H⋯O hydrogen bonds.

In the title compound, C(19)H(19)F(2)NO, the piperidinone ring adopts a chair conformation. The crystal packing is stabilized by C-H⋯O and C-H⋯F inter-molecular inter-actions, generating centrosymmetric dimers of R(2) (2)(14) and R(2) (2)(24) rings.
