1,3-Dicyclohexyl-1-(4-nitrobenzoyl)urea

Dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine–dichlorophenylborane

In the crystal structure of the title compound, C(39)H(54)BCl(2)P, the phospho-rus atom is coordinated by a dichloro-phenyl-borane unit. The substituted biphenyl group and the two cyclo-hexyl groups at the phospho-rus atom are arranged in such a way to avoid steric crowding in the mol-ecule as far as possible.

4-Amino-13-(1-naphth­yl)-[2,2]paracyclo­phane

THE TITLE COMPOUND [SYSTEMATIC NAME: 1(2)-amino-4(2)-(1-naphth-yl)-1,4(1,4)-dibenzenacyclo-hexa-phane], C(26)H(23)N, was synthesized from 4-amino-13-bromo-[2,2]paracyclo-phane and 1-naphthalene-boronic acid in the presence of 1,4-dioxane. It is a new cyclo-phane-derived compound which can be regarded as a prospective ligand for asymmetric synthesis and catalysis. The benzene rings of the paracy...

Appl Bioinformatics 2005; 4 (1): 13-24

Data management systems are fast becoming required components in many biology laboratories as the role of Abstract computer-based information grows. Although the need for data management systems is on the rise, their inherent complexities can deter the full and routine use of their computational capabilities. The significant undertaking to implement a capable production system can be reduced in...
