Cercosporin-Photocatalyzed [4+1]- and [4+2]-Annulations of Azoalkenes Under Mild Conditions

3-(4-Meth-oxy-phen-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde
None:
Four independent mol-ecules comprise the asymmetric unit of the title compound, C(17)H(14)N(2)O(2). The central pyrazoline ring is flanked by an N-bound benzene ring and a C-bound meth-oxy-substituted benzene ring. The greatest difference between the independent mol-ecules is found in the relative orientations of the benzene rings with the range of dihedral angles being 23.59 (6)-42.55 (6)°. In the crystal, extensive C-H⋯O inter-actions link mol-ecules into layers parallel to (02[Formula: see text]) and these are linked by C-H⋯π contacts.

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.
