Mol-ecules of the title compound, C(11)H(10)ClN, are essentially planar (r.m.s. deviation for all non-H atoms = 0.009 Å) and are stacked along the a axis with the centroids of the benzene and pyridine rings alternately separated by 3.649 (1) and 3.778 (1) Å.
In the title compound, C(13)H(16)ClNO, the cyclo-hexyl ring adopts a chair conformation, with puckering parameters Q = 0.576 (3) Å, θ = 0.1 (3) and ϕ = 8 (15)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link mol-ecules into one-dimensional chains propagating in [010].
The title dihaloaniline, C(6)H(5)ClIN, shows no significant hydrogen bonds nor the commonly observed I⋯I inter-actions in the crystal structure, although an amino group and an I atom are available for such contacts. The crystal structure is stabilized by weak inter-actions involving the amine functionality as donor group and N or halogen atoms as acceptors.
The reaction of 4,5-dichloro-1,2,3-dithiazolium chloride with 2-(phenylsulfonyl)acetonitrile (1 equiv) in the presence pyridine (2 gave S-(3-chloro-5-cyanoisothiazol-4-yl)benzenesulfonothioate and (Z)-2-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-2-(phenylsulfonyl)acetonitrile 19% 23% yield, respectively. compounds were fully characterized mechanistic rationale is proposed for formation benzensulfo...
Conjugate addition reaction of various nucleophiles across the vinyl group of 2-chloro-4-vinylpyrimidine, 2-chloro-4-(1-phenylvinyl)pyrimidine and 2-chloro-4-vinylquinazoline provides the corresponding 2-chloro-4-(2-substituted ethyl)pyrimidines and 2-chloro-4-(2-substituted ethyl)quinazolines. Treatment of these products, without isolation, with N-methylpiperazine results in nucleophilic displ...
