چکیده
The asymmetric unit of the title compound, C(22)H(26)N(2)O, contains three crystallographically independent mol-ecules, in which the aromatic rings are oriented at dihedral angles of 21.74 (5), 27.59 (5) and 27.87 (5)°. Intra-molecular O-H⋯N hydrogen bonds result in the formation of planar six-membered rings, and these are nearly coplanar with the adjacent rings. In the crystal structure, π-π contacts between the benzene rings [centroid-centroid distances = 3.989 (2), 3.802 (1) and 3.882 (1) Å] may stabilize the structure.

متن کاملAn unusually unstable ortho-phosphinophenol and its use to prepare benzoxaphospholes having enhanced air-stability.
The primary phosphine 3,5-di-tert-butyl-2-phosphinophenol has been prepared and characterized. Oddly, the presence of a sterically demanding tert-butyl group adjacent to the PH2 centre renders the molecule very sensitive to loss of PH3 and formation of 3,5-di-tert-butyl-phenol in chloroform solutions in the presence of air. The process was catalyzed by HCl and dependent on the purity of CDCl3. ...
