ATTEMPTED PREPARATION OF N-SUBSTITUTED DIPHENYLCYCLOPROPENEIMINE N-OXIDE
The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...
متن کاملN,N′-Dineopentylnaphthalene-1,8-diamine
In the title compound, C(20)H(30)N(2), all bond distances and angles fall within the usual ranges but the C(ipso)-N distances [1.391 (5) and 1.398 (4) Å] are slightly shorter than the corresponding typical average distance of 1.42 (3) Å. The N atoms may be described as pyramidal sp(3)-hybridized with an N-H⋯H-N separation of 2.07 (2) Å. This is necessitated because the two C(bridgehead)-C(ipso)...
متن کامل(1R,2R)-N,N′-Diisobutyl-N,N′-dimethylcyclohexane-1,2-diamine
The title compound, C(16)H(34)N(2), is a chiral diamine with fixed R configuration at both stereogenic carbon centres of the cyclo-hexane backbone. Due to their different substituents, the two N atoms also become stereogenic. In the crystal structure, the configuration at one of the two nitro-gen centres is fixed, with the free electron pair pointing inward and the isobutyl group in a trans pos...

The asymmetric unit of the title complex, [Ni(C(16)H(20)N(2))(2)(H(2)O)(2)]Cl(2)·C(3)H(7)NO, consists of two Ni(II) atoms, each lying on an inversion center, two Cl anions, two N,N'-dibenzyl-ethane-1,2-diamine ligands, two coordinated water mol-ecules and one N,N-dimethyl-formamide solvent mol-ecule. Each Ni(II) atom is six-coordinated in a distorted octa-hedral coordination geometry, with the ...
متن کامل(1R,2R)-N,N′-Dimethylcyclohexane-1,2-diamine
The molecule of the title compound, C(8)H(18)N(2), possesses C(2) symmetry. Owing to its stereochemistry, it is used in the synthesis of chiral ligands and metal complexes for asymmetric synthesis. The cyclo-hexane ring shows a chair conformation with the amino groups in equatorial positions. Contrary to the literature, the title compound is not a liquid, but a crystalline solid at room tempera...
