Conformation and stereodynamics of 2,2'-disubstituted N,N'-diaryl ureas.
Except in the most hindered of cases, N,N'-diaryl N,N'-dimethyl ureas adopt a conformation with the two aryl rings disposed cis to one another. Variable temperature NMR studies reveal the rate at which the Ar-N bonds rotate as well as the conformational preference of ortho disubstituted ureas in which more than one cis orientation is possible. In general, a conformation in which the aryl rings ...
متن کاملMEASUREMENT OF D2O IN WATER USING 2H(?,n)1H REACTION
Utilization of Photodisintegration reaction of Deuterium, 2H(?,n)1H, is a precise technique for determining the percentage of 2H in tritiated and natural water. The 23Na(n,?)24Na reaction is a suitable ?-source for producing the 2H(?,n)1H reaction. Tehran Research Reactor was used as a neutron source for producing 24Na isotopes. The BF3 detectors were used to detect the neutron emission of H2 c...
متن کاملNovel quinazoline ring synthesis by cycloaddition of N-arylketenimines with N,N-disubstituted cyanamides.
The reaction of N-aryl-substituted ketenimines with N,N-disubstituted cyanamides or (MeS)2C=N-CN under high pressure afforded 4-(N,N-disubstituted amino) or 4-(MeS)2C=N-substituted quinazoline derivatives, respectively. These products were formed by [4+2] cycloaddition between the aza-diene moieties of the N-arylsubstituted ketenimines and cyano groups. A 4-(unsubstituted amino)quinazoline deri...
متن کاملSterically demanding and chiral N,N'-disubstituted N-heterocyclic germylenes and stannylenes.
The N,N'-dimesitylene substituted o-phenylenediamine 1 reacts with Sn[N(SiMe(3))(2)](2) under formation of the monomeric N-heterocyclic stannylene 2, while the chiral N,N'-substituted o-phenylenediamine 3 reacts with E[N(SiMe(3))(2)](2) (E = Ge, Sn) under formation of the chiral germylene 4 and the chiral stannylene 5, respectively. X-Ray diffraction studies with both stannylenes demonstrated t...
متن کاملLITHIUM PERCHLORATE MEDIATED AMINATION REACTION OF ALDEHYDES: A NOVEL METHOD FOR SYNTHESIS OF N, N-DIALKYL-p-SILYLATED AMINES*
P-Silylated N,N-dialkyl amines (5) were easily synthesized in good to excellent yield from aldehydes (1), trimethylsilyldialkylamines (2), and trimethylsilylmethylmagnesium chloride (4) in the presence of 5 M lithium perchlorate solution in diethyl ether. The reaction Of (2) with aldehyde proceeded smoothly in the LiCI0 , to give the imimum salt (3). Addition of trimethylsilylmethylrnagnes...
