Continuous Flow Chemistry: Reaction of Diphenyldiazomethane with p-Nitrobenzoic Acid
Published on: November 15, 2017
Bis(4-nitro-phen-yl) 1,3-phenyl-ene-dimethyl-ene dicarbonate
Abstract:
In the title mol-ecule, C(22)H(16)N(2)O(10), the dihedral angles between the benzene rings of the 4-nitro-phenyl groups and the central benzene ring are 32.7 (1) and 34.7 (1)°, while the dihedral angle between the two benzene rings of the 4-nitro-phenyl groups is 3.6 (2)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...
