Reactivity of 4-tert-butyldimethylsiloxy-1,2,3,6-tetrahydropyridines with hydrazines.
The reactivity of 6-(nitrophenyl or trimethoxyphenyl)-4-tert-butyldimethyl- siloxy-1,2,3,6-tetrahydropyridine derivatives with hydrazines under acid conditions is described. The structure of the products isolated - hydrazones, pyrazolines or pyridazinones - depended on the conditions used. In addition, a systematic study of the reaction outcomes was carried out by introducing variations on the ...

Vinylidene complexes [Ru(η(5)-C5H5){[double bond, length as m-dash]C[double bond, length as m-dash]C(H)R}(PPh3)L]BPh4 (, ) [L = P(OMe)3, P(OEt)3; R = Ph, p-tolyl, Bu(t), H] react with hydrazine R1NHNH2 (R1 = H, Me, Ph) to afford nitrile derivatives [Ru(η(5)-C5H5)(N[triple bond, length as m-dash]CCH2R)(PPh3)L]BPh4 (, ) and amine R1NH2. Hydroxylamine NH2OH also reacts with vinylidenes , to yield ...
متن کامل4-tert-Butylpyridinium triiodide–4-tert-butylpyridine (1/1)
The title compound, C(9)H(14)N(+)·I(3) (-)·C(9)H(13)N, consists of monoprotonated 4-tert-butyl-pyridinium cations and triiodide anions. The triiodide ion has near-symmetric linear geometry, with bond lengths of 2.9105 (4) Å (I-I) and a bond angle of 177.55 (3)° (I-I-I). For this room-temperature structure, the butyl group on the pyridine ring is disordered and has been treated as a rigid rotato...
متن کامل1-(4-tert-Butylbenzyl)-2-(4-tert-butylphenyl)-1H-benzimidazole
In the mol-ecule of the title compound, C(28)H(32)N(2), the benzimidazole ring system is almost planar [maximum deviation = 0.0221 (15) Å] and forms dihedral angles of 85.86 (4) and 32.09 (6)° with the benzene rings. In the crystal structure, mol-ecules are linked into chains running parallel to the a axis by inter-molecular C-H⋯N hydrogen bonds. The methyl groups of a tert-butyl group are rota...
متن کامل4-tert-Butylpyridinium picrate
In the title compound, C(9)H(14)N(+)·C(6)H(2)N(3)O(7) (-), the three nitro groups of the picrate anion are twisted out of the plane of the attached benzene ring; the dihedral angles are 32.8 (2), 10.5 (4) and 12.3 (4)°. The pyridinium cations and picrate anions are linked via bifurcated N-H⋯(O,O) hydrogen bonds. The ionic pairs are linked into a ribbon-like structure along [101] by C-H⋯O hydrog...
