Abstract

Abstract Single-crystal X-ray structural determinations have been made on 2-anilino-2-oxo- 5, 5-dimethyl-1, 3, 2-oxazaphosphorinane. 1; 2-(4-fluoroanilino)-2-oxo-5, 5-dimethyl-1, 3, 2- oxazaphosphorinane. 2; and 2-(4-dimethylaminoanilino)-2-oxo-5, 5-dimethyl-1, 3, 2- oxazaphosphorinane, 3. Compounds 1 and 2 are iso-structural and crystallize in the monoclinic space group P 21/c with four molecules per unit cell. The cell dimensions for 1 ...
