Synthesis and X-Ray Structural Determination of 2,4,6,8- Tetraphenyl- 2,4,6,8- Tetraazabicyclo [3.3.0] Octane
Condensation of glyoxal, formaldehyde and anilines lead to the formation of 2,4,6,8- tetraphenyl and substituted phenyl 2,4,6,8-tetraazabicyclo [3.3.0] octanes. The reactions are sensitive to pH and temperature. Ortho derivatives of anilines do not participate in this condensation. X-ray structural determination reveals a cis-dienvelope geometery about the two fused rings.
متن کاملQSAR analysis of soil sorption coefficients for polar organic chemicals: substituted anilines and phenols.
Based on descriptors of n-octanol/water partition coefficients (logKow), molecular connectivity indices, and quantum chemical parameters, several QSAR models were built to estimate the soil sorption coefficients (logKoc) of substituted anilines and phenols. Results showed that descriptor logKow plus molecular quantum chemical parameters gave poor regression models. Further study was performed t...
متن کاملDirect synthesis of anilines and nitrosobenzenes from phenols.
A one-pot synthesis of anilines and nitrosobenzenes from phenols has been developed using an ipso-oxidative aromatic substitution ((i)SOAr) process. The products are obtained in good yields under mild and metal-free conditions. The leaving group effect on reactions that proceed through mixed quionone monoketals has also been investigated and a predictive model has been established.
متن کاملDual Behavior of Iodine Species in Condensation of Anilines and Vinyl Ethers Affording 2-Methylquinolines.
A metal-free, mild and efficient method for the synthesis of 2-methylquinolines was successfully developed by condensation of anilines with vinyl ethers in the presence of catalytic amount of iodine. Modification of both pyridine and benzene moieties was easily achieved by changing only the vinyl ether and aniline. In this reaction, the iodine species was revealed to show dual behavior; molecul...
متن کاملRuthenium-catalysed synthesis of 2- and 3-substituted quinolines from anilines and 1,3-diols.
A straightforward synthesis of substituted quinolines is described by cyclocondensation of anilines with 1,3-diols. The reaction proceeds in mesitylene solution with catalytic amounts of RuCl(3)·xH(2)O, PBu(3) and MgBr(2)·OEt(2). The transformation does not require any stoichiometric additives and only produces water and dihydrogen as byproducts. Anilines containing methyl, methoxy and chloro s...
