Περίληψη:	Boron(III) subphthalocyanine analogues with enhanced electron affinity in the presence of water undergo hydrolytic cleavage of the macrocycle and deborylation, resulting in formation of noncyclic aza-bridged tris-isoindoles, which are fused derivatives of 5,10-diazatripyrrines (DATRIPY). Spectral data, kinetic studies, and DFT results allow us to suggest a plausible mechanism of DATRIPY formation, which includes nucleophilic addition of water to one of the CαNmeso bonds and its rupture as a key stage. This reaction is possible for perhalogenated or/and azasubstituted boron(III) subphthalocyanine analogues and occurs especially easily for hexachlorinated tripyrazinosubporphyrazinatoboron(III) chloride, affording the corresponding 14-amino-5,10-diazatripyrrin-1-one [DATRIPY1a] bearing fused dichloropyrazine fragments in each pyrrole unit. An X-ray diffraction study revealed that DATRIPY1a has an S-like conformation, which is stabilized by two intramolecular hydrogen bonds between pyrrolic NH groups and pyrrolenine and pyrazine nitrogens. DATRIPY1a reacts with BF3, forming a noncyclic tripyrrolic bis-boron(III) complex [BODATRIPY] in which two BF2 fragments are bonded by pyrrole-pyrrolenine and pyrrole-pyrazine coordination sites. Due to rearrangement of intramolecular H-bonds occurring in aprotic and proton donor solvents, DATRIPY1a exhibits strong solvatochromism and can also be used as a colorimetric sensor for the presence of hard anions (fluoride, hydroxide, cyanide, and cyanate).
