چکیده
The title compound, C26H24BF2N3O, comprises a boron-dipyrromethene (BODIPY) framework and a phenolic Schiff base substituent group. The BODIPY unit is close to planar [maximum deviation from the least-squares plane = 0.040 (3) Å], and forms a dihedral angle of 80.38 (13)° with the meso-substituent phenyl ring and an angle of 56.57 (13)° with the phenolic ring in the extended substituent chain. An intra-molecular O-H⋯N hydrogen bond is formed between the phenolic hydroxyl group and the Schiff base N-atom. The crystal studied was a non-merohedral twin with a BASF factor of 0.447 (3) for the two components.

2-Amino-2-seleno-5,5-dimethyl-1,3,2-dioxaphosphorinane reacts with acyl chlorides (4-chlorobenzoyl chloride or pivaloyl chloride) yielding the respective N-acyl selenophosphoramides. These derivatives do not isomerise to the related selenocarbonyl imides. X-ray study of N-(4-chlorobenzoyl)-2-amino-2-seleno-5,5-dimethyl-1,3,2-dioxaphosphorinane indicates that the selenium atom is placed in the e...
